Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Pincio
–
The Pincian Hill is a hill in the northeast quadrant of the historical center of Rome. The hill lies to the north of the Quirinal, overlooking the Campus Martius. It was outside the boundaries of the ancient city of Rome, and was not one of the Seven hills of Rome. The hill came to be known in Roman times as Collis Hortulorum and its current name comes from the Pincii, one of the families that occupied it in the 4th century AD. The Pincio as seen today was laid out in 1809-14 by Giuseppe Valadier, Valadier linked the two spaces with formal staircases broken by generous landings, and a switchback carriageway. Another version stands in the Villa Borghese gardens, embriaco had presented two prototypes of his invention at the Paris Universal Exposition in 1867 where it won prizes and great acclaim. In the gardens of the Pincian, it was Giuseppe Mazzinis urging that lined the viali with busts of notable Italians, La collina del Pincio scopre i suoi segreti La Repubblica 11 December 2014

Rome
–
Rome is a special comune and the capital of Italy. Rome also serves as the capital of the Lazio region, with 2,873,598 residents in 1,285 km2, it is also the countrys largest and most populated comune and fourth-most populous city in the European Union by population within city limits. It is the center of the Metropolitan City of Rome, which has a population of 4.3 million residents, the city is located in the central-western portion of the Italian Peninsula, within Lazio, along the shores of the Tiber. Romes history spans more than 2,500 years, while Roman mythology dates the founding of Rome at only around 753 BC, the site has been inhabited for much longer, making it one of the oldest continuously occupied sites in Europe. The citys early population originated from a mix of Latins, Etruscans and it was first called The Eternal City by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called the Caput Mundi, due to that, Rome became first one of the major centres of the Italian Renaissance, and then the birthplace of both the Baroque style and Neoclassicism. Famous artists, painters, sculptors and architects made Rome the centre of their activity, in 1871 Rome became the capital of the Kingdom of Italy, and in 1946 that of the Italian Republic. Rome has the status of a global city, Rome ranked in 2014 as the 14th-most-visited city in the world, 3rd most visited in the European Union, and the most popular tourist attraction in Italy. Its historic centre is listed by UNESCO as a World Heritage Site, monuments and museums such as the Vatican Museums and the Colosseum are among the worlds most visited tourist destinations with both locations receiving millions of tourists a year. Rome hosted the 1960 Summer Olympics and is the seat of United Nations Food, however, it is a possibility that the name Romulus was actually derived from Rome itself. As early as the 4th century, there have been alternate theories proposed on the origin of the name Roma. There is archaeological evidence of occupation of the Rome area from approximately 14,000 years ago. Evidence of stone tools, pottery and stone weapons attest to about 10,000 years of human presence, several excavations support the view that Rome grew from pastoral settlements on the Palatine Hill built above the area of the future Roman Forum. Between the end of the age and the beginning of the Iron age. However, none of them had yet an urban quality, nowadays, there is a wide consensus that the city was gradually born through the aggregation of several villages around the largest one, placed above the Palatine. All these happenings, which according to the excavations took place more or less around the mid of the 8th century BC. Despite recent excavations at the Palatine hill, the view that Rome has been indeed founded with an act of will as the legend suggests in the middle of the 8th century BC remains a fringe hypothesis. Traditional stories handed down by the ancient Romans themselves explain the earliest history of their city in terms of legend and myth

Italian language
–
By most measures, Italian, together with Sardinian, is the closest to Latin of the Romance languages. Italian is a language in Italy, Switzerland, San Marino, Vatican City. Italian is spoken by minorities in places such as France, Montenegro, Bosnia & Herzegovina, Crimea and Tunisia and by large expatriate communities in the Americas. Many speakers are native bilinguals of both standardized Italian and other regional languages, Italian is the fourth most studied language in the world. Italian is a major European language, being one of the languages of the Organisation for Security and Cooperation in Europe. It is the third most widely spoken first language in the European Union with 65 million native speakers, including Italian speakers in non-EU European countries and on other continents, the total number of speakers is around 85 million. Italian is the working language of the Holy See, serving as the lingua franca in the Roman Catholic hierarchy as well as the official language of the Sovereign Military Order of Malta. Italian is known as the language of music because of its use in musical terminology and its influence is also widespread in the arts and in the luxury goods market. Italian has been reported as the fourth or fifth most frequently taught foreign language in the world, Italian was adopted by the state after the Unification of Italy, having previously been a literary language based on Tuscan as spoken mostly by the upper class of Florentine society. Its development was influenced by other Italian languages and to some minor extent. Its vowels are the second-closest to Latin after Sardinian, unlike most other Romance languages, Italian retains Latins contrast between short and long consonants. As in most Romance languages, stress is distinctive, however, Italian as a language used in Italy and some surrounding regions has a longer history. What would come to be thought of as Italian was first formalized in the early 14th century through the works of Tuscan writer Dante Alighieri, written in his native Florentine. Dante is still credited with standardizing the Italian language, and thus the dialect of Florence became the basis for what would become the language of Italy. Italian was also one of the recognised languages in the Austro-Hungarian Empire. Italy has always had a dialect for each city, because the cities. Those dialects now have considerable variety, as Tuscan-derived Italian came to be used throughout Italy, features of local speech were naturally adopted, producing various versions of Regional Italian. Even in the case of Northern Italian languages, however, scholars are not to overstate the effects of outsiders on the natural indigenous developments of the languages

Populus
–
Populus is a genus of 25–35 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar /ˈpɒp. lər/, aspen, in the September 2006 issue of Science Magazine, the Joint Genome Institute announced that the western balsam poplar was the first tree whose full DNA code had been determined by DNA sequencing. The genus has a genetic diversity, and can grow from 15–50 m tall. The shoots are stout, with the terminal bud present, leaf size is very variable even on a single tree, typically with small leaves on side shoots, and very large leaves on strong-growing lead shoots. The leaves often turn bright gold to yellow before they fall during autumn, the flowers are mostly dioecious and appear in early spring before the leaves. They are borne in long, drooping, sessile or pedunculate catkins produced from buds formed in the axils of the leaves of the previous year. The flowers are each seated in a disk which is borne on the base of a scale which is itself attached to the rachis of the catkin. The scales are obovate, lobed, and fringed, membranous, hairy or smooth, the female flower also has no calyx or corolla, and comprises a single-celled ovary seated in a cup-shaped disk. The style is short, with two to four stigmata, variously lobed, and numerous ovules, pollination is by wind, with the female catkins lengthening considerably between pollination and maturity. Poplars of the section are often wetlands or riparian trees. The aspens are among the most important boreal broadleaf trees, Poplars and aspens are important food plants for the larvae of a large number of Lepidoptera species. Pleurotus populinus, the oyster mushroom, is found exclusively on dead wood of Populus trees in North America. The genus Populus has traditionally divided into six sections on the basis of leaf and flower characters. Recent genetic studies have supported this, confirming some previously suspected reticulate evolution due to past hybridisation and introgression events between the groups. Some species had differing relationships indicated by their nuclear DNA and chloroplast DNA sequences and they have the advantage of growing to a very large size at a rapid pace. Almost all poplars take root readily from cuttings or where broken branches lie on the ground, trees with fastigiate branching are particularly popular, and are widely grown across Europe and southwest Asia. Common poplar varieties are, G48 w22 The trees are grown from kalam or cuttings, harvested annually in January and February, most commonly used to make plywood, Yamuna Nagar in Haryana state has a large plywood industry reliant upon poplar. It is graded according to known as over, under

Basilica of Santa Maria del Popolo
–
The Basilica of Santa Maria del Popolo is an Augustinian church in Rome, Italy. It stands on the side of Piazza del Popolo, one of the most famous squares in the city. The church is hemmed in between Porta del Popolo and the Pincian Hill, Porta Flaminia was one of the gates in the Aurelian Wall as well as the starting point of Via Flaminia, the most important route from the north. The church contains works by famous artists, such as Raphael, Gian Lorenzo Bernini, Caravaggio, Alessandro Algardi, Pinturicchio, Andrea Bregno, Guillaume de Marcillat. In 1099, a chapel was built by Pope Paschal II to Our Lady over the tomb of the Domitii Ahenobarbi. Tradition has it that the site was haunted by Neros ghost or demons in the form of crows, therefore the pope chopped down the walnut tree sheltering the crows. The name del Popolo probably derives from its funding by the people of Rome, the chapel was enlarged and became a church by will of Pope Gregory IX in 1235, and was given to the Augustinian friars, who still oversee it, in 1250. Santa Maria del Popolo was reconstructed by Baccio Pontelli and Andrea Bregno in 1472-1477 on the orders of Pope Sixtus IV and was given to the congregation of Lombard friars in Rome, the result of the reconstruction was an early and excellent example of Italian Renaissance architecture. In 1655-60 the façade was modified by Gian Lorenzo Bernini, who was asked by Pope Alexander VII to update the Renaissance church to a more modern Baroque style. Façade The façade was built in early Renaissance style in the 1470s when the church was rebuilt by Pope Sixtus IV. The alterations included the addition of gables at the sides on the level, pediments above the side entrances. The architecture is attributed to Andrea Bregno but without definitive evidence. According to Ulrich Fürst the architect aimed at perfect proportioning and also at masterful restraint in the detail, in this way he succeeded in designing the best church façade in early-Renaissance Rome. The façade was built of bright Roman travertine, and it is two storeys high, the three entrances are accessed by a flight of stairs giving a feel of monumentality. The architecture is simple and dignified with four pilasters on the lower level. The side doors are surmounted by pediments and their lintels have dedicatory inscriptions referring to Pope Sixtus IV. There is a pair of arched windows above them. Bernini added the two halves of a segmental pediment on the sides of the upper level, and the curved connecting element with the rich garlands

Aurelian Walls
–
The Aurelian Walls are a line of city walls built between 271 AD and 275 AD in Rome, Italy, during the reign of the Roman Emperors Aurelian and Probus. They superseded the earlier Servian Wall built during the 4th century BC, the walls enclosed all the seven hills of Rome plus the Campus Martius and, on the right bank of the Tiber, the Trastevere district. The river banks within the city appear to have been left unfortified. The size of the enclosed area is 1,400 hectares. The full circuit ran for 19 kilometres surrounding an area of 13.7 square kilometres, the walls were constructed in brick-faced concrete,3.5 metres thick and 8 metres high, with a square tower every 100 Roman feet. In the 4th century, remodelling doubled the height of the walls to 16 metres, by 500 AD, the circuit possessed 383 towers,7,020 crenellations,18 main gates,5 postern gates,116 latrines, and 2,066 large external windows. By the third century AD, the boundaries of Rome had grown far beyond the area enclosed by the old Servian Wall, Rome had remained unfortified during the subsequent centuries of expansion and consolidation due to lack of hostile threats against the city. The citizens of Rome took great pride in knowing that Rome required no fortifications because of the stability brought by the Pax Romana and the protection of the Roman Army. However, the need for updated defences became acute during the crisis of the Third Century, when barbarian tribes flooded through the Germanic frontier and the Roman Army struggled to stop them. In 270, the barbarian Juthungi and Vandals invaded northern Italy, further trouble broke out in Rome itself in the summer of 271, when the mint workers rose in rebellion. Several thousand people died in the fighting that resulted. The construction of the walls was by far the largest building project that had taken place in Rome for many decades, the construction project was unusually left to the citizens themselves to complete as Aurelian could not afford to spare a single legionary for the project. The walls were built in the time of only five years. Progress was accelerated, and money saved, by incorporating existing buildings into the structure and these included the Amphitheatrum Castrense, the Castra Praetoria, the Pyramid of Cestius, and even a section of the Aqua Claudia aqueduct near the Porta Maggiore. As much as a sixth of the walls is estimated to have composed of pre-existing structures. An area behind the walls was cleared and sentry passages were built to enable it to be reinforced quickly in an emergency, the actual effectiveness of the wall is disputable, given the relatively small size of the citys garrison. The entire combined strength of the Praetorian Guard, cohortes urbanae, instead, they carried out hit-and-run raids against ill-defended targets. The wall was a deterrent against such tactics, parts of the wall were doubled in height by Maxentius, who also improved the watch-towers

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
