Roman Iron Age in the context of "Stone circle (Iron Age)"

In Europe, the Iron Age is the last stage of the prehistoric period and the first of the protohistoric periods, which initially meant descriptions of a particular area by Greek and Roman writers. For much of Europe, the period came to an abrupt end after conquest by the Romans, though ironworking remained the dominant technology until recent times. Elsewhere, the period lasted until the early centuries AD, and either Christianization or a new conquest in the Migration Period.Iron working was introduced to Europe in the late 11th century BC, probably from the Caucasus, and slowly spread northwards and westwards over the succeeding 500 years. For example, the Iron Age of Prehistoric Ireland begins around 500 BC, when the Greek Iron Age had already ended, and finishes around 400 AD. The use of iron and iron-working technology became widespread concurrently in Europe and Asia.

The start of the Iron Age is marked by new cultural groupings, or at least terms for them, with the Late Bronze Age Mycenaean Greece collapsing in some confusion, while in Central Europe the Urnfield culture had already given way to the Hallstatt culture. In north Italy the Villanovan culture is regarded as the start of Etruscan civilization. Like its successor La Tène culture, Hallstatt is regarded as Celtic. Further to the east and north, and in Iberia and the Balkans, there are a number of local terms for the early Iron Age culture. Roman Iron Age is a term used in the archaeology of Northern Europe (but not Britain) for the period when the unconquered peoples of the area lived under the influence of the Roman Empire.

Etruscan cities were a group of ancient settlements that shared a common Etruscan language and culture, even though they were independent city-states. They flourished over a large part of the northern half of Italy starting from the Iron Age, and in some cases reached a substantial level of wealth and power. They were eventually assimilated first by Italics and ancient Greeks in the south, then by Celts in the north and finally in Etruria itself by the growing Roman Republic.

The Etruscan names of the major cities whose names were later Romanised survived in inscriptions and are listed below. Some cities were founded by Etruscans in prehistoric times and bore entirely Etruscan names. Others, usually Italic in origin, were colonised by the Etruscans, who in turn Etruscanised their name (around 9 BC).

Germania (/dʒərˈmeɪni.ə/ jər-MAY-nee-ə; Latin: [ɡɛrˈmaːni.a]), also more specifically called Magna Germania (English: Greater Germania), Germania Libera (English: Free Germania), or Germanic Barbaricum to distinguish it from the Roman provinces of Germania Inferior and Germania Superior, was a historical region in north-central Europe during the Roman era, which was associated by Roman authors with the Germanic peoples. According to Roman geographers, this region stretched roughly from the Rhine in the west to the Vistula in the east, and to the Upper Danube in the south, and the known parts of southern Scandinavia in the north. Archaeologically, these people correspond roughly to the Roman Iron Age of those regions.

The Latin name Germania means "land of the Germani", but the etymology of the name Germani itself is uncertain. During the Gallic Wars of the 1st century BC, the Roman general Julius Caesar encountered Germani originating from beyond the Rhine. He referred to their lands beyond the Rhine as "Germania". West of the Rhine, the prosperous Roman provinces of Germania Superior and Germania Inferior, sometimes collectively referred to as "Roman Germania", were established in northeast Roman Gaul, while territories east of the Rhine remained independent of Roman control. The Roman emperors also sought to expand east of the Rhine to the Elbe, but these efforts were hampered by the victory of Arminius at the Battle of the Teutoburg Forest in 9 AD.

Proto-Norse was an Indo-European language spoken in Scandinavia that is thought to have evolved as a northern dialect of Proto-Germanic in the first centuries CE. It is the earliest stage of a characteristically North Germanic language, and the language attested in the oldest Scandinavian Elder Futhark inscriptions, spoken from around the 2nd to the 8th centuries CE (corresponding to the late Roman Iron Age and the Germanic Iron Age). It evolved into the dialects of Old Norse at the beginning of the Viking Age around 800 CE, which later themselves evolved into the modern North Germanic languages (Faroese, Icelandic, the Continental Scandinavian languages, and their dialects).

There is some evidence that, in addition to being a writing system, runes historically served purposes of magic. This is the case from the earliest epigraphic evidence of the Roman to the Germanic Iron Age, with non-linguistic inscriptions and the alu word. An erilaz appears to have been a person versed in runes, including their magic applications.

In medieval sources, notably the Poetic Edda, the Sigrdrífumál mentions "victory runes" to be carved on a sword, "some on the grasp and some on the inlay, and name Tyr twice."

The Gundestrup cauldron is a richly decorated silver vessel, thought to date from between 200 BC and 300 AD, or more narrowly between 150 BC and 1 BC. This places it within the late La Tène period or early Roman Iron Age. The cauldron is the largest known example of European Iron Age silver work (diameter: 69 cm (27 in); height: 42 cm (17 in)). It was found dismantled, with the other pieces stacked inside the base, in 1891, in a peat bog near the hamlet of Gundestrup in the Aars parish of Himmerland, Denmark (56°49′N 9°33′E / 56.817°N 9.550°E / 56.817; 9.550). It is now usually on display in the National Museum of Denmark in Copenhagen, with replicas at other museums; it was in the UK on a travelling exhibition called The Celts during 2015–2016.

The cauldron is not complete, and now consists of a rounded cup-shaped bottom making up the lower part of the cauldron, usually called the base plate, above which are five interior plates and seven exterior ones; a missing eighth exterior plate would be needed to encircle the cauldron, and only two sections of a rounded rim at the top of the cauldron survive. The base plate is mostly smooth and undecorated inside and out, apart from a decorated round medallion in the centre of the interior. All the other plates are heavily decorated with repoussé work, hammered from beneath to push out the silver. Other techniques were used to add detail, and there is extensive gilding and some use of inlaid pieces of glass for the eyes of figures. Other pieces of fittings were found. Altogether it weighs just under 9 kilograms (20 lb).
