Paleohispanic scripts
–
The Paleohispanic scripts are the writing systems created in the Iberian peninsula before the Latin alphabet became the dominant script. Most of them are unusual in that they are rather than purely alphabetic, despite having supposedly developed, in part. Some researchers conclude that their origin may lie solely with the Phoenician alphabet, the Paleoiberian scripts are classified into three major groups, southern, northern, and Greco-Iberian, with differences both in the shapes of the glyphs and in their values. Inscriptions in the scripts have been found mainly in the southern half of the Iberian Peninsula. They represent only 5% of the inscriptions found, and mostly read from right to left and they are, the Espanca script, the Tartessian or Southwestern script, also known as South Lusitanian, the Southeastern Iberian script, also known as Meridional. Inscriptions in the scripts have been found mainly in the NE of the Iberian Peninsula. They represent 95% of the inscriptions found, and mostly read from left to right and they are, the Northeastern Iberian script, also known as Levantine, Dual variant Non-dual variant the Celtiberian script Western variant Eastern variant. This unique writing system has been called a semi-syllabary, in addition, the original format did not distinguish voiced from unvoiced plosives, so that ga stood for both /ga/ and /ka/, and da stood for both /da/ and /ta/. On the other hand, the continuants were written with simple alphabetic letters, as in Phoenician, if correct, this innovation would parallel the creation of the Latin letter G by the addition of a stroke to C, which had previously stood for both /k/ and /g/. The Tartessian script is typologically intermediate between a pure alphabet and the Paleohispanic semi-syllabaries, although the letter used to write a plosive was determined by the following vowel, as in a semi-syllabary, the following vowel was also written, as in an alphabet. This redundant typology re-emerged in a few texts of northeastern Iberian and Celtiberian scripts. The only known full Paleoiberian signary, on the undated Espanca tablet, follows the Phoenician/Greek order for the first 13 of its 27 letters, Α Β Γ Δ Ι Κ Λ Μ Ν Ξ Π. However, the order of what appears to be /u/ directly after Τ, the obvious question about the origin and evolution of these scripts is how a purely alphabetic script was changed into, or perhaps unconsciously reinterpreted as, a partial syllabary. It may be instructive to consider an unrelated development in the evolution of the Etruscan alphabet from Greek, Greek had three letters, Γ, Κ, and Ϙ, whose sounds were not distinguished in Etruscan. Nonetheless, all three were borrowed, becoming the letters C, K, and Q. When the Etruscan alphabet was adapted to Latin, the letter C stood for both /k/ and /g/, as Etruscan had had no /g/ sound to maintain the original sound value of Greek Г. Something similar may have happened during the evolution of the Paleoiberian scripts, in Tartessian script, vowels were always written after the plosives, but they were redundant — or at nearly so — and thus it seems they were dropped when the script passed to the Iberians. Among the velar consonants, ka/ga of southeastern Iberian and the southwestern script derives from Phoenician/Greek Γ, ke/ge from Κ, Phoenician/Greek labial letter Β was the source of southwestern be, southeastern ba, the use of Π is uncertain but may have been the source of bi

Navarre
–
The first documented use of a name resembling Navarra, Nafarroa, or Naparroa is a reference to navarros, in Eginhards early 9th Century chronicle of the feats of the Holy Roman Emperor Charlemagne. Other Royal Frankish Annals feature nabarros, there are two proposed etymologies for the name. Basque nabar, brownish, multicolor (i. e. in contrast to the mountainous lands north of the original County of Navarre. Basque naba, valley, plain + Basque herri, the linguist Joan Coromines considers naba to be linguistically part of a wider Vasconic or Aquitanian language substrate, rather than Basque per se. During the Roman Empire, the Vascones, a tribe who populated the southern slopes of the Pyrenees. In the mountainous north, the Vascones escaped large-scale Roman settlement, not so the flatter areas to the south, which were amenable to large-scale Roman farming—vineyards, olives, and wheat crops. Neither the Visigoths nor the Franks ever completely subjugated the area, the Vascones included neighbouring tribes as of the 7th century. In AD778, the Basques defeated a Frankish army at the Battle of Roncevaux Pass and that kingdom reached its zenith during the reign of King Sancho III, comprising most of the Christian realms to the south of the Pyrenees, and even a short overlordship of Gascony. When Sancho III died in 1035, the Kingdom of Navarre was divided between his sons and it never fully recovered its political power, while its commercial importance increased as traders and pilgrims poured into the kingdom throughout the Way of Saint James. In 1200, Navarre lost the key western Basque districts to Alphonse VIII of Castile, Navarre then contributed with a small but symbolic force of 200 knights to the decisive Battle of Las Navas de Tolosa in 1212 against the Almohads. The native line of kings came to an end in 1234, however, the Navarrese kept most of their strong laws and institutions. To the south of the Pyrenees, Navarre was annexed to the Crown of Castile, but keeping a separate status. A Chartered Government was established, and the managed to keep home rule. After the 1839 Convention of Bergara, a version of home rule was passed in 1839. The relocation of customs from the Ebro river to the Pyrenees in 1841 prompted the collapse of Navarre’s customary cross-Pyrenean trade, amid instability in Spain, Carlists took over in Navarre and the rest of the Basque provinces. The end of the Third Carlist War saw a wave of Spanish centralization directly affecting Navarre. In 1893-1894 the Gamazada popular uprising took place centred in Pamplona against Madrids governmental decisions breaching the 1841 chartered provisions. Except for a faction, all parties in Navarre agreed on the need for a new political framework based on home rule within the Laurak Bat

Greek alphabet
–
It is the ancestor of the Latin and Cyrillic scripts. In its classical and modern forms, the alphabet has 24 letters, Modern and Ancient Greek use different diacritics. In standard Modern Greek spelling, orthography has been simplified to the monotonic system, examples In both Ancient and Modern Greek, the letters of the Greek alphabet have fairly stable and consistent symbol-to-sound mappings, making pronunciation of words largely predictable. Ancient Greek spelling was generally near-phonemic, among consonant letters, all letters that denoted voiced plosive consonants and aspirated plosives in Ancient Greek stand for corresponding fricative sounds in Modern Greek. This leads to groups of vowel letters denoting identical sounds today. Modern Greek orthography remains true to the spellings in most of these cases. The following vowel letters and digraphs are involved in the mergers, Modern Greek speakers typically use the same, modern, in other countries, students of Ancient Greek may use a variety of conventional approximations of the historical sound system in pronouncing Ancient Greek. Several letter combinations have special conventional sound values different from those of their single components, among them are several digraphs of vowel letters that formerly represented diphthongs but are now monophthongized. In addition to the three mentioned above, there is also ⟨ου⟩, pronounced /u/, the Ancient Greek diphthongs ⟨αυ⟩, ⟨ευ⟩ and ⟨ηυ⟩ are pronounced, and respectively in voicing environments in Modern Greek. The Modern Greek consonant combinations ⟨μπ⟩ and ⟨ντ⟩ stand for and respectively, ⟨τζ⟩ stands for, in addition, both in Ancient and Modern Greek, the letter ⟨γ⟩, before another velar consonant, stands for the velar nasal, thus ⟨γγ⟩ and ⟨γκ⟩ are pronounced like English ⟨ng⟩. There are also the combinations ⟨γχ⟩ and ⟨γξ⟩ and these signs were originally designed to mark different forms of the phonological pitch accent in Ancient Greek. The letter rho, although not a vowel, also carries a rough breathing in word-initial position, if a rho was geminated within a word, the first ρ always had the smooth breathing and the second the rough breathing leading to the transiliteration rrh. The vowel letters ⟨α, η, ω⟩ carry an additional diacritic in certain words, the iota subscript. This iota represents the former offglide of what were originally long diphthongs, ⟨ᾱι, ηι, ωι⟩, another diacritic used in Greek is the diaeresis, indicating a hiatus. In 1982, a new, simplified orthography, known as monotonic, was adopted for use in Modern Greek by the Greek state. Although it is not a diacritic, the comma has a function as a silent letter in a handful of Greek words, principally distinguishing ό. There are many different methods of rendering Greek text or Greek names in the Latin script, the form in which classical Greek names are conventionally rendered in English goes back to the way Greek loanwords were incorporated into Latin in antiquity. In this system, ⟨κ⟩ is replaced with ⟨c⟩, the diphthongs ⟨αι⟩ and ⟨οι⟩ are rendered as ⟨ae⟩ and ⟨oe⟩ respectively, and ⟨ει⟩ and ⟨ου⟩ are simplified to ⟨i⟩ and ⟨u⟩ respectively

Writing system
–
A writing system is any conventional method of visually representing verbal communication. While both writing and speech are useful in conveying messages, writing differs in also being a form of information storage. The processes of encoding and decoding writing systems involve shared understanding between writers and readers of the meaning behind the sets of characters that make up a script, the general attributes of writing systems can be placed into broad categories such as alphabets, syllabaries, or logographies. Any particular system can have attributes of more than one category, in the alphabetic category, there is a standard set of letters of consonants and vowels that encode based on the general principle that the letters represent speech sounds. In a syllabary, each symbol correlates to a syllable or mora, in a logography, each character represents a word, morpheme, or other semantic units. Other categories include abjads, which differ from alphabets in that vowels are not indicated, alphabets typically use a set of 20-to-35 symbols to fully express a language, whereas syllabaries can have 80-to-100, and logographies can have several hundreds of symbols. Systems will also enable the stringing together of these groupings in order to enable a full expression of the language. The reading step can be accomplished purely in the mind as an internal process, writing systems were preceded by proto-writing, which used pictograms, ideograms and other mnemonic symbols. Proto-writing lacked the ability to capture and express a range of thoughts. Soon after, writing provided a form of long distance communication. With the advent of publishing, it provided the medium for a form of mass communication. Writing systems are distinguished from other possible symbolic communication systems in that a system is always associated with at least one spoken language. In contrast, visual representations such as drawings, paintings, and non-verbal items on maps, such as contour lines, are not language-related. Some other symbols, such as numerals and the ampersand, are not directly linked to any specific language, every human community possesses language, which many regard as an innate and defining condition of humanity. However, the development of writing systems, and the process by which they have supplanted traditional oral systems of communication, have been sporadic, uneven, once established, writing systems generally change more slowly than their spoken counterparts. Thus they often preserve features and expressions which are no current in the spoken language. One of the benefits of writing systems is that they can preserve a permanent record of information expressed in a language. In the examination of individual scripts, the study of writing systems has developed along partially independent lines, thus, the terminology employed differs somewhat from field to field

Coin
–
A coin is a small, flat, round piece of metal or plastic used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in quantities at a mint in order to facilitate trade. They are most often issued by a government, Coins are usually metal or alloy, or sometimes made of synthetic materials. Coins made of metal are stored in large quantities as bullion coins. Other coins are used as money in transactions, circulating alongside banknotes. Usually the highest value coin in circulation is less than the lowest-value note. In the last hundred years, the value of circulation coins has occasionally been lower than the value of the metal they contain. Exceptions to the rule of face value being higher than content value also occur for some bullion coins made of copper, silver, or gold, while the Eagle, Maple Leaf, and Sovereign coins have nominal face values, the Krugerrand does not. The first coins were developed independently in Iron Age Anatolia and Archaic Greece, India, Coins spread rapidly in the 6th and 5th centuries BCE, throughout Greece and Persia, and further to the Balkans. Standardized Roman currency was used throughout the Roman Empire, important Roman gold and silver coins were continued into the Middle Ages. Fiat money first arose in medieval China, with the paper money. Early paper money was introduced in Europe in the later Middle Ages, the penny was minted as a silver coin until the 17th century. The first circulating United States coins were cents, produced in 1793, Coins were an evolution of currency systems of the Late Bronze Age, where standard-sized ingots, and tokens such as knife money, were used to store and transfer value. In the late Chinese Bronze Age, standardized cast tokens were made and these were replicas in bronze of earlier Chinese currency, cowrie shells, so they were named Bronze Shell. According to Aristotle and Pollux, the first issuer of coins was Hermodike of Kyme The earliest coins are associated with Iron Age Anatolia. Early electrum coins were not standardized in weight, and in their earliest stage may have been ritual objects, such as badges or medals, issued by priests. The first Lydian coins were made of electrum, a naturally occurring alloy of silver, most of the early Lydian coins include no writing, only an image of a symbolic animal. Anatolian Artemis was the Πὀτνια Θηρῶν, whose symbol was the stag, a small percentage of early Lydian/Greek coins have a legend

Ancient Rome
–
In its many centuries of existence, the Roman state evolved from a monarchy to a classical republic and then to an increasingly autocratic empire. Through conquest and assimilation, it came to dominate the Mediterranean region and then Western Europe, Asia Minor, North Africa and it is often grouped into classical antiquity together with ancient Greece, and their similar cultures and societies are known as the Greco-Roman world. Ancient Roman civilisation has contributed to modern government, law, politics, engineering, art, literature, architecture, technology, warfare, religion, language and society. Rome professionalised and expanded its military and created a system of government called res publica, the inspiration for modern republics such as the United States and France. By the end of the Republic, Rome had conquered the lands around the Mediterranean and beyond, its domain extended from the Atlantic to Arabia, the Roman Empire emerged with the end of the Republic and the dictatorship of Augustus Caesar. 721 years of Roman-Persian Wars started in 92 BC with their first war against Parthia and it would become the longest conflict in human history, and have major lasting effects and consequences for both empires. Under Trajan, the Empire reached its territorial peak, Republican mores and traditions started to decline during the imperial period, with civil wars becoming a prelude common to the rise of a new emperor. Splinter states, such as the Palmyrene Empire, would divide the Empire during the crisis of the 3rd century. Plagued by internal instability and attacked by various migrating peoples, the part of the empire broke up into independent kingdoms in the 5th century. This splintering is a landmark historians use to divide the ancient period of history from the pre-medieval Dark Ages of Europe. King Numitor was deposed from his throne by his brother, Amulius, while Numitors daughter, Rhea Silvia, because Rhea Silvia was raped and impregnated by Mars, the Roman god of war, the twins were considered half-divine. The new king, Amulius, feared Romulus and Remus would take back the throne, a she-wolf saved and raised them, and when they were old enough, they returned the throne of Alba Longa to Numitor. Romulus became the source of the citys name, in order to attract people to the city, Rome became a sanctuary for the indigent, exiled, and unwanted. This caused a problem for Rome, which had a large workforce but was bereft of women, Romulus traveled to the neighboring towns and tribes and attempted to secure marriage rights, but as Rome was so full of undesirables they all refused. Legend says that the Latins invited the Sabines to a festival and stole their unmarried maidens, leading to the integration of the Latins, after a long time in rough seas, they landed at the banks of the Tiber River. Not long after they landed, the men wanted to take to the sea again, one woman, named Roma, suggested that the women burn the ships out at sea to prevent them from leaving. At first, the men were angry with Roma, but they realized that they were in the ideal place to settle. They named the settlement after the woman who torched their ships, the Roman poet Virgil recounted this legend in his classical epic poem the Aeneid

Ancient Greece
–
Ancient Greece was a civilization belonging to a period of Greek history from the Greek Dark Ages of the 12th-9th centuries BC to the end of antiquity. Immediately following this period was the beginning of the Early Middle Ages and this was followed by the period of Classical Greece, an era that began with the Greco-Persian Wars, lasting from the 5th to 4th centuries BC. Due to the conquests by Alexander the Great of Macedonia, Hellenistic civilization flourished from Central Asia to the end of the Mediterranean Sea. Classical Greek culture, especially philosophy, had a influence on ancient Rome. For this reason Classical Greece is generally considered to be the culture which provided the foundation of modern Western culture and is considered the cradle of Western civilization. Classical Antiquity in the Mediterranean region is considered to have begun in the 8th century BC. Classical Antiquity in Greece is preceded by the Greek Dark Ages and this period is succeeded, around the 8th century BC, by the Orientalizing Period during which a strong influence of Syro-Hittite, Jewish, Assyrian, Phoenician and Egyptian cultures becomes apparent. The end of the Dark Ages is also dated to 776 BC. The Archaic period gives way to the Classical period around 500 BC, Ancient Periods Astronomical year numbering Dates are approximate, consult particular article for details The history of Greece during Classical Antiquity may be subdivided into five major periods. The earliest of these is the Archaic period, in which artists made larger free-standing sculptures in stiff, the Archaic period is often taken to end with the overthrow of the last tyrant of Athens and the start of Athenian Democracy in 508 BC. It was followed by the Classical period, characterized by a style which was considered by observers to be exemplary, i. e. classical, as shown in the Parthenon. This period saw the Greco-Persian Wars and the Rise of Macedon, following the Classical period was the Hellenistic period, during which Greek culture and power expanded into the Near and Middle East. This period begins with the death of Alexander and ends with the Roman conquest, Herodotus is widely known as the father of history, his Histories are eponymous of the entire field. Herodotus was succeeded by authors such as Thucydides, Xenophon, Demosthenes, Plato, most of these authors were either Athenian or pro-Athenian, which is why far more is known about the history and politics of Athens than those of many other cities. Their scope is limited by a focus on political, military and diplomatic history, ignoring economic. In the 8th century BC, Greece began to emerge from the Dark Ages which followed the fall of the Mycenaean civilization, literacy had been lost and Mycenaean script forgotten, but the Greeks adopted the Phoenician alphabet, modifying it to create the Greek alphabet. The Lelantine War is the earliest documented war of the ancient Greek period and it was fought between the important poleis of Chalcis and Eretria over the fertile Lelantine plain of Euboea. Both cities seem to have suffered a decline as result of the long war, a mercantile class arose in the first half of the 7th century BC, shown by the introduction of coinage in about 680 BC

Iberian Peninsula
–
The Iberian Peninsula /aɪˈbɪəriən pəˈnɪnsjᵿlə/, also known as Iberia /aɪˈbɪəriə/, is located in the southwest corner of Europe. The peninsula is divided between Portugal and Spain, comprising most of their territory. With an area of approximately 582,000 km2, it is the second largest European peninsula, at that time, the name did not describe a single political entity or a distinct population of people. Strabos Iberia was delineated from Keltikē by the Pyrenees and included the land mass southwest of there. The ancient Greeks reached the Iberian Peninsula, of which they had heard from the Phoenicians, hecataeus of Miletus was the first known to use the term Iberia, which he wrote about circa 500 BC. Herodotus of Halicarnassus says of the Phocaeans that it was they who made the Greeks acquainted with. According to Strabo, prior historians used Iberia to mean the country side of the Ἶβηρος as far north as the river Rhône in France. Polybius respects that limit, but identifies Iberia as the Mediterranean side as far south as Gibraltar, elsewhere he says that Saguntum is on the seaward foot of the range of hills connecting Iberia and Celtiberia. Strabo refers to the Carretanians as people of the Iberian stock living in the Pyrenees, according to Charles Ebel, the ancient sources in both Latin and Greek use Hispania and Hiberia as synonyms. The confusion of the words was because of an overlapping in political, the Latin word Hiberia, similar to the Greek Iberia, literally translates to land of the Hiberians. This word was derived from the river Ebro, which the Romans called Hiberus, hiber was thus used as a term for peoples living near the river Ebro. The first mention in Roman literature was by the annalist poet Ennius in 200 BC. Virgil refers to the Ipacatos Hiberos in his Georgics, the Roman geographers and other prose writers from the time of the late Roman Republic called the entire peninsula Hispania. As they became interested in the former Carthaginian territories, the Romans began to use the names Hispania Citerior. At the time Hispania was made up of three Roman provinces, Hispania Baetica, Hispania Tarraconensis, and Lusitania, Strabo says that the Romans use Hispania and Iberia synonymously, distinguishing between the near northern and the far southern provinces. Whatever language may generally have been spoken on the peninsula soon gave way to Latin, except for that of the Vascones, the Iberian Peninsula has always been associated with the Ebro, Ibēros in ancient Greek and Ibērus or Hibērus in Latin. The association was so known it was hardly necessary to state, for example. Pliny goes so far as to assert that the Greeks had called the whole of Spain Hiberia because of the Hiberus River, the river appears in the Ebro Treaty of 226 BC between Rome and Carthage, setting the limit of Carthaginian interest at the Ebro. The fullest description of the treaty, stated in Appian, uses Ibērus, with reference to this border, Polybius states that the native name is Ibēr, apparently the original word, stripped of its Greek or Latin -os or -us termination

Alicante
–
It is also a historic Mediterranean port. The population of the city of Alicante proper was 328,648, estimated as of 2015, including nearby municipalities, the Alicante conurbation had 452,462 residents. The population of the area was 757,085 as of 2014 estimates. The name of the city echoes the Arabic name Laqant or Al-Laqant, the area around Alicante has been inhabited for over 7000 years. The first tribes of hunter-gatherers moved down gradually from Central Europe between 5000 and 3000 BC, some of the earliest settlements were made on the slopes of Mount Benacantil. The town of Leuce Akra was then founded by Greek settlers from Marseille around 325/324 b. C, by the 3rd century BC, the rival armies of Carthage and Rome began to invade and fight for control of the Iberian Peninsula. The Carthaginian general Hamilcar Barca established the settlement of Akra Leuka. Although the Carthaginians conquered much of the land around Alicante, the Romans would eventually rule Hispania Tarraconensis for over 700 years. By the 5th century AD, Rome was in decline and the Roman predecessor town of Alicante, however neither the Romans nor the Goths put up much resistance to the Arab conquest of Medina Laqant in the 8th century. The Moors ruled southern and eastern Spain until the 13th century Reconquista, Alicante was finally taken in 1246 by the Castilian king Alfonso X, but it passed soon and definitively to the Kingdom of Valencia in 1298 with King James II of Aragon. It gained the status of Royal Village with representation in the medieval Valencian Parliament and this act cost the region dearly, with so many skilled artisans and agricultural labourers gone, the feudal nobility found itself sliding into bankruptcy. The end of the 19th century witnessed a sharp recovery of the economy with increasing international trade. During the early 20th century, Alicante was a capital that enjoyed the benefit of Spains neutrality during World War I. The Rif War in the 1920s saw numerous alicantinos drafted to fight in the long, the political unrest of the late 1920s led to the victory of Republican candidates in local council elections throughout the country, and the abdication of King Alfonso XIII. The proclamation of the Second Spanish Republic was much celebrated in the city on 14 April 1931, the Spanish Civil War broke out on 17 July 1936. The late 1950s and early 1960s saw the onset of a transformation of the city by the tourist industry. New construction benefited the economy, as the development of the tourism sector also spawned new businesses such as restaurants, bars. When Franco died in 1975, his successor Juan Carlos I played his part as the symbol of the transition of Spain to a democratic constitutional monarchy

Ebro
–
The Ebro or Ebre is one of the most important rivers on the Iberian Peninsula. It is the second longest river in the Iberian peninsula after the Tagus, the source of the river Ebro is in Fontibre, from the Latin words Fontes Iberis, source of the Ebro. Close by is the big artificial lake Embalse del Ebro created by the damming of the river, the upper Ebro rushes through rocky gorges in Burgos Province. Karst geological processes shaped the landscape of layers of carbonate rock of extensive limestone bedrock formed in an ancient seabed. Aragonite, a named for Aragon, attests to the fact that carbonates are abundant in the central Ebro Valley. The valley expands and the Ebros flow then becomes slower as its volume increases. There, larger tributaries flowing from the Central Pyrenees and the Iberian System discharge large amounts of water, as it flows through Zaragoza the Ebro, is already a sizeable river. There, the Basilica of Our Lady of the Pillar stands next to the Ebro, the soils in most of the valley are primarily poor soils, calcareous, pebbly, stony, and sometimes salted with saltwater endorheic lagoons. The semi-arid interior of the Ebro Valley has either drought summers and it is covered with chaparral vegetation. Summers are hot and winters are cold, the dry summer season has temperatures of more than 35 °C, occasionally reaching over 40 °C. In winter, the temperatures drop below 0 °C. In some areas the vegetation depends heavily on moisture produced by condensation fogs and it is a continental Mediterranean climate with extreme temperatures. There are many ground frosts on clear nights, and sporadic snowfalls, the biomes are diverse in these Mediterranean climate zones, Mediterranean forests, woodlands, and scrub. Hinterlands are particularly distinctive on account of extensive sclerophyll shrublands known as maquis, the dominant species are Quercus coccifera and Quercus ilex. These trees form monospecific communities or communities integrated with Pinus, Mediterranean buckthorns, Myrtus, Chamaerops humilis, junipers, Pistacia, Rosmarinus, Thymus, etc. The mountain vegetation is mostly coniferous forests that are drought adapted and their presence is related to the marine origin of the Ebro valley and the extensive marine deposits in the same area. After reaching Catalonia, the Ebro Valley narrows, and the river becomes constrained by mountain ranges, massive dams have been built in this area, such as the dams at Mequinenza, Riba-roja, Flix. In the final section of its course the river bends southwards, the massive calcareous cliffs of the Serra de Cardó range constrain the river during this last stretch, separating the Ebro Valley from the Mediterranean coastal area

Silver
–
Silver is a metallic element with symbol Ag and atomic number 47. The symbol Ag stems from Latin argentum, derived from the Greek ὰργὀς, a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earths crust in the pure, free form, as an alloy with gold and other metals. Most silver is produced as a byproduct of copper, gold, lead, Silver is more abundant than gold, but it is much less abundant as a native metal. Its purity is measured on a per mille basis, a 94%-pure alloy is described as 0.940 fine. As one of the seven metals of antiquity, silver has had a role in most human cultures. Silver has long valued as a precious metal. Silver metal is used in many premodern monetary systems in bullion coins, Silver is used in numerous applications other than currency, such as solar panels, water filtration, jewelry, ornaments, high-value tableware and utensils, and as an investment medium. Silver is used industrially in electrical contacts and conductors, in specialized mirrors, window coatings, Silver compounds are used in photographic film and X-rays. Dilute silver nitrate solutions and other compounds are used as disinfectants and microbiocides, added to bandages and wound-dressings, catheters. Silver is similar in its physical and chemical properties to its two neighbours in group 11 of the periodic table, copper and gold. This distinctive electron configuration, with an electron in the highest occupied s subshell over a filled d subshell. Silver is a soft, ductile and malleable transition metal. Silver crystallizes in a cubic lattice with bulk coordination number 12. Unlike metals with incomplete d-shells, metallic bonds in silver are lacking a covalent character and are relatively weak and this observation explains the low hardness and high ductility of single crystals of silver. Silver has a brilliant white metallic luster that can take a polish. Protected silver has greater optical reflectivity than aluminium at all wavelengths longer than ~450 nm, at wavelengths shorter than 450 nm, silvers reflectivity is inferior to that of aluminium and drops to zero near 310 nm. The electrical conductivity of silver is the greatest of all metals, greater even than copper, during World War II in the US,13540 tons of silver were used in electromagnets for enriching uranium, mainly because of the wartime shortage of copper

Bronze
–
These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness, ductility, or machinability. The archeological period where bronze was the hardest metal in use is known as the Bronze Age. In the ancient Near East this began with the rise of Sumer in the 4th millennium BC, with India and China starting to use bronze around the same time, everywhere it gradually spread across regions. The Bronze Age was followed by the Iron Age starting from about 1300 BC and reaching most of Eurasia by about 500 BC, the discovery of bronze enabled people to create metal objects which were harder and more durable than previously possible. Bronze tools, weapons, armor, and building such as decorative tiles were harder and more durable than their stone. It was only later that tin was used, becoming the major ingredient of bronze in the late 3rd millennium BC. Tin bronze was superior to arsenic bronze in that the process could be more easily controlled. Also, unlike arsenic, metallic tin and fumes from tin refining are not toxic, the earliest tin-alloy bronze dates to 4500 BCE in a Vinča culture site in Pločnik. Other early examples date to the late 4th millennium BC in Africa, Susa and some ancient sites in China, Luristan, ores of copper and the far rarer tin are not often found together, so serious bronze work has always involved trade. Tin sources and trade in ancient times had a influence on the development of cultures. In Europe, a source of tin was the British deposits of ore in Cornwall. In many parts of the world, large hoards of bronze artefacts are found, suggesting that bronze also represented a store of value, in Europe, large hoards of bronze tools, typically socketed axes, are found, which mostly show no signs of wear. With Chinese ritual bronzes, which are documented in the inscriptions they carry and from other sources and these were made in enormous quantities for elite burials, and also used by the living for ritual offerings. Pure iron is soft, and the process of beating and folding sponge iron to wrought iron removes from the metal carbon. Careful control of the alloying and tempering eventually allowed for wrought iron with properties comparable to modern steel, Bronze was still used during the Iron Age, and has continued in use for many purposes to the modern day. Among other advantages, it does not rust, the weaker wrought iron was found to be sufficiently strong for many uses. Archaeologists suspect that a disruption of the tin trade precipitated the transition. The population migrations around 1200–1100 BC reduced the shipping of tin around the Mediterranean, limiting supplies, there are many different bronze alloys, but typically modern bronze is 88% copper and 12% tin
