Answer the following question: Information: - The La Tene culture was a European Iron Age culture named after the archaeological site of La Tene on the north side of Lake Neuchatel in Switzerland, where thousands of objects had been deposited in the lake, as was discovered after the water level dropped in 1857. La Tene is the type site and the term archaeologists use for the later period of the culture and art of the ancient Celts, a term that is firmly entrenched in the popular understanding, but presents numerous problems for historians and archaeologists. The culture became very widespread, and presents a wide variety of local differences. It is often distinguished from earlier and neighbouring cultures mainly by the La Tene style of Celtic art, characterized by curving "swirly" decoration, especially of metalwork. - Belgium , officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of and has a population of about 11million people. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch-speaking, mostly Flemish community, which constitutes about 59% of the population, and the French-speaking, mostly Walloon population, which comprises 41% of all Belgians. Additionally, there is a small group of German-speakers who live in the East Cantons located around the High Fens area, and bordering Germany. - Gaius Julius Caesar (13 July 100BC 15 March 44BC), known as Julius Caesar, was a Roman politician, general, and notable author of Latin prose. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire. - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux. - Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state. - The Cimbri were an ancient people, either Germanic or Celtic who, together with the Teutones and the Ambrones, fought the Roman Republic between 113 and 101 BC. The Cimbri were initially successful, particularly at the Battle of Arausio, in which a large Roman army was routed, after which they raided large areas in Gaul and Hispania. In 101 BC, during an attempted invasion of Italy, the Cimbri were decisively defeated by Gaius Marius, and their king, Boiorix, was killed. Some of the surviving captives are reported to have been among the rebelling Gladiators in the Third Servile War. - Raetia (or , , also spelled Rhaetia) was a province of the Roman Empire, named after the Rhaetian ("Raeti" or "Rhaeti") people. It bordered on the west with the country of the Helvetii, on the east with Noricum, on the north with Vindelicia, on the west with Transalpine Gaul and on south with Venetia et Histria. It thus comprised the districts occupied in modern times by eastern and central Switzerland (containing the Upper Rhine and Lake Constance), southern Bavaria and the Upper Swabia, Vorarlberg, the greater part of Tirol, and part of Lombardy. Later Vindelicia (today south-eastern Wuerttemberg and south-western Bavaria) formed part of Raetia. The northern border of Raetia during the times of Augustus and Tiberius was the River Danube. Later the Limes Germanicus marked the northern boundary, stretching for 166km north of the Danube. Raetia linked to Italy across the Alps over the Reschen Pass, by the Via Claudia Augusta. The Romansh people living in Southeast Switzerland are believed to be direct descendants of the Raetians. However, the exact lineage of the Romansh (or Romansch) people remains incomplete. - Saint Castor of Apt ( died ca . 420 ) was a bishop of Apt , bishop during Gaul . He was born in Nimes and may have been the brother of Saint Leontius of Frejus . Castor was a lawyer and married to a wealthy widow . He lived in Marseilles . His wife , however , allowed him to enter the religious life ; she herself entered a nunnery . Castor founded the monastery of Manauque ( Monanque ) in Provence . He was subsequently made bishop of Apt. He died of natural causes . Saint John Cassian wrote the De institutis coenobiorum at the request of Castor . His feast day is September 2 . His relics are still preserved in the cathedral of Apt , of which he is one of the patrons . - The Rhine (, , ) is a European river that begins in the Swiss canton of Graubunden in the southeastern Swiss Alps, forms part of the Swiss-Austrian, Swiss-Liechtenstein, Swiss-German and then the Franco-German border, then flows through the Rhineland and eventually empties into the North Sea in the Netherlands. The largest city on the river Rhine is Cologne, Germany, with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe (after the Danube), at about , with an average discharge of about . - Northern Italy is a cultural and geographical region, without any administrative purpose, used to indicate the northern part of the Italian state, also informally referred as "Il Nord", "Settentrione" or "Alta Italia". It consists of 8 regions in northern Italy: Aosta Valley, Piedmont, Liguria, Lombardy, Emilia-Romagna, Veneto, Friuli-Venezia Giulia, Trentino-Alto Adige/Sudtirol. According to the 2011 census, its population was 27,213,372. For statistic purposes, the Istituto Nazionale di Statistica (ISTAT) uses the term Northwest Italy and Northeast Italy for identifying two of the five statistical regions in its reporting. These same subdivisions are used to demarcate first level Nomenclature of Territorial Units for Statistics (NUTS) regions ("NUTS 1 regions") within the European Union, and the Italian constituencies for the European Parliament. - Gaul (Latin: "Gallia") was a region of Western Europe during the Iron Age that was inhabited by Celtic tribes, encompassing present day France, Luxembourg, Belgium, most of Switzerland, Northern Italy, as well as the parts of the Netherlands, Central Italy and Germany on the west bank of the Rhine. It covered an area of 190,800mi or 494,169km. According to the testimony of Julius Caesar, Gaul was divided into three parts: Gallia Celtica, Belgica and Aquitania. Archaeologically, the Gauls were bearers of the La Tene culture, which extended across all of Gaul, as well as east to Raetia, Noricum, Pannonia and southwestern Germania during the 5th to 1st centuries BC. During the 2nd and 1st centuries BC, Gaul fell under Roman rule: Gallia Cisalpina was conquered in 203 BC and Gallia Narbonensis in 123 BC. Gaul was invaded after 120BC by the Cimbri and the Teutons, who were in turn defeated by the Romans by 103BC. Julius Caesar finally subdued the remaining parts of Gaul in his campaigns of 58 to 51BC. - Noricum is the Latin name for a Celtic kingdom, or federation of tribes, that included most of modern Austria and part of Slovenia. In the first century AD, it became a province of the Roman Empire. Its borders were the Danube to the north, "Raetia" and "Vindelicia" to the west, Pannonia to the east and southeast, and "Italia" ("Venetia et Histria") to the south. The kingdom was founded around 400 BC, and had its capital at the royal residence at Virunum on the Magdalensberg. - The Iron Age is an archaeological era, referring to a period of time in the prehistory and protohistory of the Old World (Afro-Eurasia) when the dominant toolmaking material was iron. It is commonly preceded by the Bronze Age in Europe and Asia with exceptions and the Stone Age in Africa. Meteoric iron has been used by humans since at least 3200 BC, but ancient iron production did not become widespread until the ability to smelt iron ore, remove impurities and regulate the amount of carbon in the alloy were developed. The start of the Iron Age proper is considered by many to fall between around 1200 BC to 600 BC, depending on the region. In most parts of the world, its end is defined by the widespread adoption of writing, and therefore marks the transition from prehistory to history.
