Lutetia in the context of "Julian the Apostate"

Gratian (/ˈɡreɪʃiən/; Latin: Gratianus; 18 April 359 – 25 August 383) was emperor of the Western Roman Empire from 367 to 383. The eldest son of Valentinian I, Gratian was raised to the rank of Augustus as a child and inherited the West after his father's death in 375. He nominally shared the government with his infant half-brother Valentinian II, who was also acclaimed emperor in Pannonia on Valentinian's death. The East was ruled by his uncle Valens, who was later succeeded by Theodosius I.

Gratian subsequently led a campaign across the Rhine, attacked the Lentienses, and forced the tribe to surrender. That same year, the eastern emperor Valens was killed fighting the Goths at the Battle of Adrianople, which led to Gratian elevating Theodosius to replace him in 379. Gratian favoured Nicene Christianity over traditional Roman religion, issuing the Edict of Thessalonica, refusing the office of pontifex maximus, and removing the Altar of Victory from the Roman Senate's Curia Julia. The city of Cularo on the Isère river in Roman Gaul was renamed Gratianopolis after him, which later evolved to Grenoble. By 383 Gratian had become unpopular with his army, which abandoned him during a confrontation with the usurper Magnus Maximus near Lutetia (Paris). Gratian fled to Lugdunum and was later murdered.

The 1st arrondissement of Paris (I arrondissement) is one of the 20 arrondissements of the capital city of France. In spoken French, this arrondissement is colloquially referred to as le premier (the first). It is governed locally together with the 2nd, 3rd and 4th arrondissement, with which it forms the 1st sector of Paris (Paris-Centre).

Also known as Louvre, the arrondissement is situated principally on the right bank of the River Seine. It also includes the west end of the Île de la Cité. The locality is one of the oldest areas in Paris, the Île de la Cité having been the heart of the city of Lutetia, conquered by the Romans in 52 BC, while some parts on the right bank (including Les Halles) date back to the early Middle Ages.

The Pont Neuf (French pronunciation: [pɔ̃ nœf], "New Bridge") is the oldest standing bridge across the river Seine in Paris, France. It stands by the western (downstream) point of the Île de la Cité, the island in the middle of the river that was, between 250 and 225 BC, the birthplace of Paris, then known as Lutetia and, during the medieval period, the heart of the city.

The bridge is composed of two separate spans, one of five arches joining the left bank to the Île de la Cité, another of seven joining the island to the right bank. Old engraved maps of Paris show that the newly built bridge just grazed the downstream tip of the Île de la Cité; since then, the natural sandbar building of a mid-river island, aided by stone-faced embankments called quais, has extended the island. Today the tip of the island is the location of the Square du Vert-Galant, a small public park named in honour of Henry IV, nicknamed the "Green Gallant".

21 Lutetia is a large M-type asteroid in the main asteroid belt. It measures about 100 kilometers in diameter (120 km along its major axis). It was discovered in 1852 by Hermann Goldschmidt, and is named after Lutetia, the Latin name of Paris.

Lutetia has an irregular shape and is heavily cratered, with the largest impact crater reaching 45 km in diameter. The surface is geologically heterogeneous and is intersected by a system of grooves and scarps, which are thought to be fractures. It has a high overall bulk density, suggesting that it is made of metal-rich rock.

The Pillar of the Boatmen (French: Pilier des nautes) is a monumental Roman column erected in Lutetia (modern Paris) in honour of Jupiter by the guild of boatmen in the 1st century AD. It is the oldest monument in Paris and is one of the earliest pieces of representational Gallo-Roman art to carry a written inscription.

The Roman name for the monument is Nautae Parisiaci (the sailors of the Parisii, who were a tribe of Gauls). It was found re-used in the 4th century city wall on the Île de la Cité and is now displayed in the frigidarium of the Thermes de Cluny.

Denis of Paris (Latin: Dionysius) was a 3rd-century Christian martyr and saint. According to his hagiographies, he was bishop of Paris (then Lutetia) in the third century and, together with his companions Rusticus and Eleutherius, was martyred for his faith by decapitation. Some accounts placed this during Domitian's persecution and incorrectly identified St Denis of Paris with the Areopagite who was converted by Paul the Apostle and who served as the first bishop of Athens. Assuming Denis's historicity, it is now considered more likely that he suffered under the persecution of the emperor Decius shortly after AD 250.

Denis is the most famous cephalophore in Christian history, with a popular story claiming that the decapitated bishop picked up his head and walked several miles while preaching a sermon on repentance. He is venerated in the Catholic Church as a patron saint of both France and Paris and is one of the Fourteen Holy Helpers. A chapel was raised at the site of his burial by a local Christian woman; it was later expanded into an abbey and basilica, around which grew up the French city of Saint-Denis, now a suburb of Paris.

The oldest traces of human occupation in Paris date from about 8000 BC, during the Mesolithic period. Between 250 and 225 BC, the Parisii settled on the banks of the Seine, built bridges and a fort, minted coins, and began to trade with other river settlements in Europe. In 52 BC, a Roman army led by Titus Labienus defeated the Parisii and established a Gallo-Roman garrison town called Lutetia. The town was Christianised in the 3rd century AD, and after the collapse of the Roman Empire, it was occupied by Clovis I, the King of the Franks, who made it his capital in 508.

During the Middle Ages, Paris was the largest city in Europe, an important religious and commercial centre, and the birthplace of the Gothic style of architecture. The University of Paris on the Left Bank, organised in the mid-13th century, was one of the first in Europe. It suffered from the Bubonic Plague in the 14th century and the Hundred Years' War in the 15th century, with recurrence of the plague. Between 1418 and 1436, the city was occupied by the Burgundians and English. In the 16th century, Paris became the book-publishing capital of Europe, though it was shaken by the French Wars of Religion between Catholics and Protestants. In the 18th century, Paris was the centre of the intellectual ferment known as the Enlightenment, and the main stage of the French Revolution from 1789. In the 19th century, Napoleon embellished the city with monuments to military glory. It became the European capital of fashion and the scene of two more revolutions (in 1830 and 1848). The centre of Paris was rebuilt between 1852 and 1870 with wide new avenues, squares and new parks, and the city was expanded to its present limits in 1860. In the latter part of the century, millions of tourists came to see the Paris International Expositions and the new Eiffel Tower.
