Tiberius
Tiberius was a Roman Emperor from 14 AD to 37 AD. Born Tiberius Claudius Nero, a Claudian, Tiberius was the son of Tiberius Claudius Nero and his mother divorced Nero and married Octavian, known as Augustus, in 39 BC, making him a step-son of Octavian. Tiberius would marry Augustus daughter, Julia the Elder, and even be adopted by Augustus, by which act he officially became a Julian, bearing the name Tiberius Julius Caesar. The subsequent emperors after Tiberius would continue this blended dynasty of both families for the thirty years, historians have named it the Julio-Claudian dynasty. In relations to the emperors of this dynasty, Tiberius was the stepson of Augustus, grand-uncle of Caligula, paternal uncle of Claudius. Tiberius was one of Romes greatest generals, his conquest of Pannonia, Dalmatia and temporarily, parts of Germania, laid the foundations for the northern frontier. But he came to be remembered as a dark and sombre ruler who never really desired to be emperor, Pliny the Elder called him tristissimus hominum, after the death of Tiberius’ son Drusus Julius Caesar in 23 AD, he became more reclusive and aloof.
In 26 AD Tiberius removed himself from Rome and left largely in the hands of his unscrupulous Praetorian Prefects Lucius Aelius Sejanus and Quintus Naevius Sutorius Macro. Caligula, Tiberius grand-nephew and adopted grandson, succeeded Tiberius upon his death, Tiberius was born in Rome on 16 November 42 BC to Tiberius Claudius Nero and Livia Drusilla. In 39 BC his mother divorced his father and remarried Gaius Julius Caesar Octavianus shortly thereafter. In 38 BC his brother, Nero Claudius Drusus, was born, little is recorded of Tiberiuss early life. In 32 BC Tiberius at the age of nine, delivered the eulogy for his father at the rostra. In 29 BC, both he rode in the chariot along with their adoptive father Octavian in celebration of the defeat of Antony. In 23 BC Emperor Augustus became gravely ill and his possible death threatened to plunge the Roman world into chaos again, in response, a series of potential heirs seem to have been selected, among them Tiberius and his brother Drusus. Similar provisions were made for Drusus, shortly thereafter Tiberius began appearing in court as an advocate, and it is presumably here that his interest in Greek rhetoric began.
In 20 BC, Tiberius was sent East under Marcus Agrippa, the Parthians had captured the standards of the legions under the command of Marcus Licinius Crassus, Decidius Saxa, and Marc Antony. Augustus was able to reach a compromise whereby the standards were returned, Tiberius married Vipsania Agrippina, the daughter of Augustus’s close friend and greatest general, Marcus Vipsanius Agrippa. He was appointed to the position of praetor, and sent with his legions to assist his brother Drusus in campaigns in the west
Gold
Gold is a chemical element with symbol Au and atomic number 79. In its purest form, it is a bright, slightly yellow, soft, malleable. Chemically, gold is a metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions, Gold often occurs in free elemental form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the element silver and naturally alloyed with copper. Less commonly, it occurs in minerals as gold compounds, often with tellurium, golds atomic number of 79 makes it one of the higher numbered, naturally occurring elements. It is thought to have produced in supernova nucleosynthesis, from the collision of neutron stars. Because the Earth was molten when it was formed, almost all of the present in the early Earth probably sank into the planetary core. Gold is resistant to most acids, though it does dissolve in aqua regia, a mixture of acid and hydrochloric acid. Gold dissolves in solutions of cyanide, which are used in mining and electroplating.
Gold dissolves in mercury, forming amalgam alloys, but this is not a chemical reaction, as a precious metal, gold has been used for coinage and other arts throughout recorded history. A total of 186,700 tonnes of gold is in existence above ground, the world consumption of new gold produced is about 50% in jewelry, 40% in investments, and 10% in industry. Gold is used in infrared shielding, colored-glass production, gold leafing, certain gold salts are still used as anti-inflammatories in medicine. As of 2014, the worlds largest gold producer by far was China with 450 tonnes, Gold is cognate with similar words in many Germanic languages, deriving via Proto-Germanic *gulþą from Proto-Indo-European *ǵʰelh₃-. The symbol Au is from the Latin, the Latin word for gold, the Proto-Indo-European ancestor of aurum was *h₂é-h₂us-o-, meaning glow. This word is derived from the root as *h₂éu̯sōs, the ancestor of the Latin word Aurora. This etymological relationship is presumably behind the frequent claim in scientific publications that aurum meant shining dawn, Gold is the most malleable of all metals, a single gram can be beaten into a sheet of 1 square meter, and an avoirdupois ounce into 300 square feet.
Gold leaf can be thin enough to become semi-transparent
Vespasian
Vespasian was Roman emperor from AD69 to AD79. Vespasian founded the Flavian dynasty that ruled the Empire for twenty-seven years, Vespasian was from an equestrian family that rose into the senatorial rank under the Julio–Claudian emperors. While Vespasian besieged Jerusalem during the Jewish rebellion, emperor Nero committed suicide, after Galba and Otho perished in quick succession, Vitellius became the third emperor in April 69. The Roman legions of Roman Egypt and Judaea reacted by declaring Vespasian, their commander, emperor on 1 July 69. In his bid for power, Vespasian joined forces with Mucianus, the governor of Syria, and Primus. Primus and Mucianus led the Flavian forces against Vitellius, while Vespasian took control of Egypt, on 20 December 69, Vitellius was defeated, and the following day Vespasian was declared Emperor by the Senate. Little information survives about the government during Vespasians ten-year rule and he reformed the financial system at Rome after the campaign against Judaea ended successfully, and initiated several ambitious construction projects.
He began the building of the Flavian Amphitheatre, better known today as the Roman Colosseum, in reaction to the events of 68–69, Vespasian forced through an improvement in army discipline. Through his general Agricola, Vespasian increased imperial expansion in Britain, after his death in 79, he was succeeded by his eldest son Titus, thus becoming the first Roman Emperor to be directly succeeded by his own natural son and establishing the Flavian dynasty. Vespasian was born in a village north-east of Rome called Falacrinae and his family was relatively undistinguished and lacking in pedigree. His paternal grandfather, Titus Flavius Petro, became the first to himself, rising to the rank of centurion. Subsequently he became a debt collector, petros son, Titus Flavius Sabinus, worked as a customs official in the province of Asia and became a money-lender on a small scale among the Helvetii. He gained a reputation as a scrupulous and honest tax-farmer, Sabinus married up in status, to Vespasia Polla, whose father had risen to the rank of prefect of the camp and whose brother became a Senator.
Sabinus and Vespasia had three children, the eldest of whom, a girl, died in infancy, the elder boy, Titus Flavius Sabinus entered public life and pursued the cursus honorum. He served in the army as a tribune in Thrace in 36. The following year he was elected quaestor and served in Crete, the younger boy, seemed far less likely to be successful, initially not wishing to pursue high public office. He followed in his brothers footsteps when driven to it by his mothers taunting, during this period he married Flavia Domitilla, the daughter of Flavius Liberalis from Ferentium and formerly the mistress of Statilius Capella, a Roman equestrian from Sabrata in Africa. They had two sons, Titus Flavius Vespasianus and Titus Flavius Domitianus, and a daughter and his wife Domitilla and his daughter Domitilla both died before Vespasian became Emperor in 69
Nero
Nero was Roman Emperor from 54 to 68, and the last in the Julio-Claudian dynasty. Nero was adopted by his great-uncle Claudius to become his heir and successor, during his reign, the redoubtable general Corbulo conducted a successful war and negotiated peace with the Parthian Empire. His general Suetonius Paulinus crushed a revolt in Britain, Nero annexed the Bosporan Kingdom to the empire and may have begun the First Jewish–Roman War. In 64 AD, most of Rome was destroyed in the Great Fire of Rome, writing a generation later, claims that many Romans believed Nero himself had started the fire, in order to clear land for his planned palatial complex, the Domus Aurea. In 68, the rebellion of Vindex in Gaul and the acclamation of Galba in Hispania drove Nero from the throne, facing a false report of being denounced as a public enemy who was to be executed, he committed suicide on 9 June 68. His death ended the Julio-Claudian dynasty, sparking a period of civil wars known as the Year of the Four Emperors.
Neros rule is often associated with tyranny and extravagance and he is known for many executions, including that of his mother, and the probable murder by poison of his stepbrother Britannicus. Nero was rumored to have had captured Christians dipped in oil and this view is based on the writings of Tacitus and Cassius Dio, the main surviving sources for Neros reign, but a few sources paint Nero in a more favourable light. Some sources, including some mentioned above, portray him as an emperor who was popular with the common Roman people, some modern historians question the reliability of ancient sources when reporting on Neros tyrannical acts. Lucius Domitius Ahenobarbus, was born on 15 December 37 in Antium and he was the only son of Gnaeus Domitius Ahenobarbus and Agrippina the Younger, sister of Emperor Caligula. Neros father, was the son of Lucius Domitius Ahenobarbus, Gnaeus was thus the grandson of Gnaeus Domitius Ahenobarbus and probably Aemilia Lepida on his fathers side, and the grandson of Mark Antony and Octavia Minor on his mothers side.
Thus, Nero had as his paternal grandmother Antonia Major, through Octavia, Nero was the great-nephew of Caesar Augustus. Neros father had employed as a praetor and was a member of Caligulas staff when the latter travelled to the East. Neros father was described by Suetonius as a murderer and a cheat who was charged by Emperor Tiberius with treason, Tiberius died, allowing him to escape these charges. Neros father died of edema in 39 when Nero was two, Neros mother was Agrippina the Younger, a great-granddaughter of Caesar Augustus and his wife Scribonia through their daughter Julia the Elder and her husband Marcus Vipsanius Agrippa. Agrippinas father, was a grandson of Augustuss wife, Livia, on one side and Mark Antony, Germanicus mother Antonia Minor was a daughter of Octavia Minor and Mark Antony. Germanicus was the son of Tiberius. Agrippina poisoned her second husband Passienus Crispus, so many ancient historians accuse her of murdering her third husband, the emperor Claudius
Copper
Copper is a chemical element with symbol Cu and atomic number 29. It is a soft and ductile metal with high thermal and electrical conductivity. A freshly exposed surface of copper has a reddish-orange color. Copper is one of the few metals that occur in nature in directly usable metallic form as opposed to needing extraction from an ore and this led to very early human use, from c.8000 BC. Copper used in buildings, usually for roofing, oxidizes to form a green verdigris, Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as agents and wood preservatives. Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the enzyme complex cytochrome c oxidase. In molluscs and crustaceans, copper is a constituent of the blood pigment hemocyanin, replaced by the hemoglobin in fish. In humans, copper is found mainly in the liver, the adult body contains between 1.4 and 2.1 mg of copper per kilogram of body weight.
The filled d-shells in these elements contribute little to interatomic interactions, unlike metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak. This observation explains the low hardness and high ductility of single crystals of copper, at the macroscopic scale, introduction of extended defects to the crystal lattice, such as grain boundaries, hinders flow of the material under applied stress, thereby increasing its hardness. For this reason, copper is supplied in a fine-grained polycrystalline form. The softness of copper partly explains its high conductivity and high thermal conductivity. The maximum permissible current density of copper in open air is approximately 3. 1×106 A/m2 of cross-sectional area, Copper is one of a few metallic elements with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air, as with other metals, if copper is put in contact with another metal, galvanic corrosion will occur. A green layer of verdigris can often be seen on old structures, such as the roofing of many older buildings.
Copper tarnishes when exposed to sulfur compounds, with which it reacts to form various copper sulfides. There are 29 isotopes of copper, 63Cu and 65Cu are stable, with 63Cu comprising approximately 69% of naturally occurring copper, both have a spin of 3⁄2
Roman Empire
Civil wars and executions continued, culminating in the victory of Octavian, Caesars adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavians power was unassailable and in 27 BC the Roman Senate formally granted him overarching power, the imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. The first two centuries of the empires existence were a period of unprecedented political stability and prosperity known as the Pax Romana, following Octavians victory, the size of the empire was dramatically increased. After the assassination of Caligula in 41, the senate briefly considered restoring the republic, under Claudius, the empire invaded Britannia, its first major expansion since Augustus. Vespasian emerged triumphant in 69, establishing the Flavian dynasty, before being succeeded by his son Titus and his short reign was followed by the long reign of his brother Domitian, who was eventually assassinated.
The senate appointed the first of the Five Good Emperors, the empire reached its greatest extent under Trajan, the second in this line. A period of increasing trouble and decline began with the reign of Commodus, Commodus assassination in 192 triggered the Year of the Five Emperors, of which Septimius Severus emerged victorious. The assassination of Alexander Severus in 235 led to the Crisis of the Third Century in which 26 men were declared emperor by the Roman Senate over a time span. It was not until the reign of Diocletian that the empire was fully stabilized with the introduction of the Tetrarchy, which saw four emperors rule the empire at once. This arrangement was unsuccessful, leading to a civil war that was finally ended by Constantine I. Constantine subsequently shifted the capital to Byzantium, which was renamed Constantinople in his honour and it remained the capital of the east until its demise. Constantine adopted Christianity which became the state religion of the empire. However, Augustulus was never recognized by his Eastern colleague, and separate rule in the Western part of the empire ceased to exist upon the death of Julius Nepos.
The Eastern Roman Empire endured for another millennium, eventually falling to the Ottoman Turks in 1453, the Roman Empire was among the most powerful economic, cultural and military forces in the world of its time. It was one of the largest empires in world history, at its height under Trajan, it covered 5 million square kilometres. It held sway over an estimated 70 million people, at that time 21% of the entire population. Throughout the European medieval period, attempts were made to establish successors to the Roman Empire, including the Empire of Romania, a Crusader state. Rome had begun expanding shortly after the founding of the republic in the 6th century BC, then, it was an empire long before it had an emperor
Rye
Rye is a grass grown extensively as a grain, a cover crop and a forage crop. It is a member of the tribe and is closely related to barley. Rye grain is used for flour, rye bread, rye beer, crisp bread, some whiskeys, some vodkas and it can be eaten whole, either as boiled rye berries or by being rolled, similar to rolled oats. Rye is a grain and should not be confused with ryegrass, which is used for lawns, pasture. Rye is one of a number of species grow wild in central and eastern Turkey. It is possible that rye traveled west from Turkey as an admixture in wheat. Since the Middle Ages people have cultivated rye widely in Central and it serves as the main bread cereal in most areas east of the French-German border and north of Hungary. In Southern Europe, it was cultivated on marginal lands, claims of much earlier cultivation of rye, at the Epipalaeolithic site of Tell Abu Hureyra in the Euphrates valley of northern Syria remain controversial. Critics point to inconsistencies in the dates, and identifications based solely on grain.
Winter rye is any breed of rye planted in the fall to provide cover for the winter. It grows during warmer days of the winter when sunlight temporarily warms the plant above freezing and it is sometimes used in winter gardens and is a common nurse crop. Rye is grown primarily in Eastern and Northern Europe, the main rye belt stretches from northern Germany through Poland, Belarus and Latvia into central and northern Russia. Rye is grown in North America, in South America, in Oceania, in Turkey, in Kazakhstan, production levels of rye have fallen in most of the producing nations, as of 2012. For instance, production of rye in Russia fell from 13.9 million metric tons in 1992 to 2.1 t in 2012, most rye is consumed locally or exported only to neighboring countries, rather than being shipped worldwide. Rye is highly susceptible to the ergot fungus, consumption of ergot-infected rye by humans and animals results in a serious medical condition known as ergotism. Ergotism can cause physical and mental harm, including convulsions, necrosis of digits, hallucinations.
Historically, damp northern countries that have depended on rye as a staple crop were subject to epidemics of this condition. There have been occurrence of ergotism with periods where there were incidents of people persecuted for being witches
Antoninus Pius
Antoninus Pius, known as Antoninus, was Roman Emperor from 138 to 161. He was one of the Five Good Emperors in the Nerva–Antonine dynasty and he died of illness in 161 and was succeeded by his adopted sons Marcus Aurelius and Lucius Verus as co-emperors. He was born as the child of Titus Aurelius Fulvus. The Aurelii Fulvii were therefore a new senatorial family from Gallia Narbonensis whose rise to prominence was supported by the Flavians. The link between Antoninus family and their home province explains the importance of the post of Proconsul of Gallia Narbonensis during the late Second Century. Antoninus was born near Lanuvium and his mother was Arria Fadilla, the Arrii Antoninii were an older senatorial family from Italy, very influential during Nervas reign. Arria Fadilla, Antoninus mother, married afterwards Publius Julius Lupus, a man of rank, suffect consul in 98. Some time between 110 and 115, Antoninus married Annia Galeria Faustina the Elder and they are believed to have enjoyed a happy marriage.
Faustina was the daughter of consul Marcus Annius Verus and Rupilia Faustina, Faustina was a beautiful woman, and despite rumours about her character, it is clear that Antoninus cared for her deeply. Faustina bore Antoninus four children, two sons and two daughters and they were, Marcus Aurelius Fulvus Antoninus, his sepulchral inscription has been found at the Mausoleum of Hadrian in Rome. Marcus Galerius Aurelius Antoninus, his sepulchral inscription has been found at the Mausoleum of Hadrian in Rome and his name appears on a Greek Imperial coin. Aurelia Fadilla, she married Lucius Lamia Silvanus, consul 145 and she appeared to have no children with her husband and her sepulchral inscription has been found in Italy. Annia Galeria Faustina Minor or Faustina the Younger, a future Roman Empress, married her maternal cousin, when Faustina died in 141, Antoninus was greatly distressed. In honour of her memory, he asked the Senate to deify her as a goddess and he had various coins with her portrait struck in her honor.
These coins were scripted ‘DIVA FAUSTINA’ and were elaborately decorated and he further created a charity which he founded and called it Puellae Faustinianae or Girls of Faustina, which assisted destitute girls of good family. Finally, Antoninus created a new alimenta, instead, he lived with Galena Lysistrata, one of Faustinas freed women. Concubinage was a form of female companionship sometimes chosen by powerful men in Ancient Rome, especially widowers like Vespasian and their union could not produce any legitimate offspring who could threaten any heirs, such as those of Antoninus. Also, as one could not have a wife and a concubine at the same time
Postumus
Marcus Cassianius Latinius Postumus was a Roman commander of provincial origin who ruled as emperor in the west. He ruled for the part of ten years before he was murdered by his own troops. Little is known about the life of Postumus. He has been claimed as a Batavian, certainly his coinage honours deities—Hercules Magusanus, Hercules Magusanus was probably an interpretatio romana translation of the Germanic deity Donar. Deusoniensis may refer to the town of Deuso, located in or near Batavian territory and likely to be identified with Diessen, from these relatively obscure provincial origins, Postumus would have risen through the ranks of the army until he held command of the Roman forces among the Celts. What his precise title was is not definitely known, though he may plausibly have been promoted by the emperor Valerian to the position of imperial legate of Lower Germany, Postumus was evidently in favour at court, according to König, was granted an honorary consulship. By 259, Valerian was campaigning in the east against the Persians, while his son, Gallienus left his son and military commanders, including Postumus, to protect the Rhine.
Amid the chaos of an invasion by the Alamanni and Franks, and spurred on by news of the defeat and capture of Valerian, the army in Gaul revolted and proclaimed Postumus emperor. The trigger was their defeat in 260 of a Juthungian army which was returning from Italy laden with prisoners, under the command of Postumus and Marcus Simplicinius Genialis, the Roman army crushed the Juthungi, and Postumus proceeded to distribute the captured spoils to the legions he commanded. Saloninus, on the advice of his praetorian prefect Silvanus, demanded the transfer of the booty to his residence at Colonia Claudia Ara Agrippinensium. Postumus assembled his army and made a show of reluctantly enforcing this command, the troops accordingly proclaimed Postumus emperor and proceeded to besiege and attack Colonia Claudia Ara Agrippinensium, trapping Saloninus and Silvanus. After breaching the walls of the city, Postumus had Silvanus and Saloninus killed, Later he erected a triumphal arch to celebrate his victory.
Postumus was immediately recognized as emperor in Gaul, the two Germanias, and Raetia, by 261, Gallia Narbonensis and Hispania had acknowledged him as emperor, possibly after an expedition to Britain in the winter of 260/261. Apart from the position of emperor, he assumed the office of consul alongside a colleague. Like his imperial predecessors, he became the pontifex maximus of the state, reflecting his power base, the chief members of Postumus’ administration appeared to have been of northern Gallic origin, and indeed, the entire administration soon became rapidly Gallicized. Both Victorinus and Tetricus, important members of the government, hailed from this region, scholars continue to debate whether Postumus originally intended to dislodge Gallienus from Rome or was content to rule only the western provinces. From the beginning of his usurpation, Postumus had made it clear that he had no intentions to make a bid for Rome. Postumus’ powerbase was Gaul and his responsibility was the defense of the Rhine provinces
Lead
Lead is a chemical element with atomic number 82 and symbol Pb. When freshly cut, it is bluish-white, it tarnishes to a dull gray upon exposure to air and it is a soft and heavy metal with a density exceeding that of most common materials. Lead has the second-highest atomic number of the stable elements. Lead is a relatively unreactive post-transition metal and its weak metallic character is illustrated by its amphoteric nature and tendency to form covalent bonds. Compounds of lead are found in the +2 oxidation state. Exceptions are mostly limited to organolead compounds, like the lighter members of the group, lead exhibits a tendency to bond to itself, it can form chains and polyhedral structures. Lead is easily extracted from its ores and was known to people in Western Asia. A principal ore of lead, often bears silver, Lead production declined after the fall of Rome and did not reach comparable levels again until the Industrial Revolution. Nowadays, global production of lead is about ten million tonnes annually, Lead has several properties that make it useful, high density, low melting point and relative inertness to oxidation.
In the late 19th century, lead was recognized as poisonous, Lead is a neurotoxin that accumulates in soft tissues and bones, damaging the nervous system and causing brain disorders and, in mammals, blood disorders. A lead atom has 82 electrons, arranged in a configuration of 4f145d106s26p2. The combined first and second ionization energies—the total energy required to remove the two 6p electrons—is close to that of tin, leads upper neighbor in group 14. This is unusual since ionization energies generally fall going down a group as an elements outer electrons become more distant from the nucleus, the similarity is caused by the lanthanide contraction—the decrease in element radii from lanthanum to lutetium, and the relatively small radii of the elements after hafnium. The contraction is due to shielding of the nucleus by the lanthanide 4f electrons. The combined first four ionization energies of lead exceed those of tin, for this reason lead, unlike tin, mostly forms compounds in which it has an oxidation state of +2, rather than +4.
Relativistic effects, which become particularly prominent at the bottom of the periodic table, as a result, the 6s electrons of lead become reluctant to participate in bonding, a phenomenon called the inert pair effect. A related outcome is that the distance between nearest atoms in crystalline lead is unusually long, the lighter group 14 elements form stable or metastable allotropes having the tetrahedrally coordinated and covalently bonded diamond cubic structure. The energy levels of their outer s- and p-orbitals are close enough to allow mixing into four hybrid sp3 orbitals
Augustus
Augustus was the founder of the Roman Principate and considered the first Roman emperor, controlling the Roman Empire from 27 BC until his death in AD14. He was born Gaius Octavius into an old and wealthy equestrian branch of the plebeian gens Octavia and his maternal great-uncle Julius Caesar was assassinated in 44 BC, and Octavius was named in Caesars will as his adopted son and heir, known as Octavianus. He, Mark Antony, and Marcus Lepidus formed the Second Triumvirate to defeat the assassins of Caesar, following their victory at the Battle of Philippi, the Triumvirate divided the Roman Republic among themselves and ruled as military dictators. The Triumvate was eventually torn apart by the ambitions of its members. Lepidus was driven into exile and stripped of his position, in reality, however, he retained his autocratic power over the Republic as a military dictator. By law, Augustus held a collection of powers granted to him for life by the Senate, including supreme military command, and it took several years for Augustus to develop the framework within which a formally republican state could be led under his sole rule.
He rejected monarchical titles, and instead called himself Princeps Civitatis, the resulting constitutional framework became known as the Principate, the first phase of the Roman Empire. The reign of Augustus initiated an era of peace known as the Pax Romana. Augustus dramatically enlarged the Empire, annexing Egypt, Pannonia and Raetia, expanding possessions in Africa, expanding into Germania, beyond the frontiers, he secured the Empire with a buffer region of client states and made peace with the Parthian Empire through diplomacy. Augustus died in AD14 at the age of 75 and he probably died from natural causes, although there were unconfirmed rumors that his wife Livia poisoned him. He was succeeded as Emperor by his adopted son Tiberius, Augustus was known by many names throughout his life, At birth, he was named Gaius Octavius after his biological father. Historians typically refer to him simply as Octavius between his birth in 63 until his adoption by Julius Caesar in 44 BC, upon his adoption, he took Caesars name and became Gaius Julius Caesar Octavianus in accordance with Roman adoption naming standards.
He quickly dropped Octavianus from his name, and his contemporaries referred to him as Caesar during this period, historians. In 27 BC, following his defeat of Mark Antony and Cleopatra and it is the events of 27 BC from which he obtained his traditional name of Augustus, which historians use in reference to him from 27 BC until his death in AD14. While his paternal family was from the town of Velletri, approximately 40 kilometres from Rome and he was born at Ox Head, a small property on the Palatine Hill, very close to the Roman Forum. He was given the name Gaius Octavius Thurinus, his cognomen possibly commemorating his fathers victory at Thurii over a band of slaves. Due to the nature of Rome at the time, Octavius was taken to his fathers home village at Velletri to be raised. Octavius only mentions his fathers equestrian family briefly in his memoirs and his paternal great-grandfather Gaius Octavius was a military tribune in Sicily during the Second Punic War
Brass
Brass is a metal alloy made of copper and zinc, the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is an alloy, atoms of the two constituents may replace each other within the same crystal structure. By comparison, bronze is principally an alloy of copper and tin, however and brass may include small proportions of a range of other elements including arsenic, aluminium and silicon. The term is applied to a variety of brasses. Modern practice in museums and archaeology increasingly avoids both terms for objects in favour of the all-embracing copper alloy. It is used in zippers, Brass is often used in situations in which it is important that sparks not be struck, such as in fittings and tools used near flammable or explosive materials. Brass has higher malleability than bronze or zinc, the relatively low melting point of brass and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard, the density of brass is 8.4 to 8.73 grams per cubic centimetre.
Today, almost 90% of all alloys are recycled. Because brass is not ferromagnetic, it can be separated from ferrous scrap by passing the scrap near a powerful magnet, Brass scrap is collected and transported to the foundry where it is melted and recast into billets. Billets are heated and extruded into the form and size. The general softness of brass means that it can often be machined without the use of cutting fluid, aluminium makes brass stronger and more corrosion-resistant. Aluminium causes a highly beneficial hard layer of oxide to be formed on the surface that is thin, transparent. Tin has an effect and finds its use especially in seawater applications. Combinations of iron, aluminium and manganese make brass wear and tear resistant, to enhance the machinability of brass, lead is often added in concentrations of around 2%. Since lead has a melting point than the other constituents of the brass. The pattern the globules form on the surface of the brass increases the available surface area which in turn affects the degree of leaching.
In addition, cutting operations can smear the lead globules over the surface and these effects can lead to significant lead leaching from brasses of comparatively low lead content
