History of Germany between 800 BC - 251 BC
In Europe, the Iron Age may be defined as including the last stages of the prehistoric period and the first of the proto-historic periods. The Iron Age in Europe is characterized by an elaboration of designs in weapons, implements, and utensils. These are no longer cast but hammered into shape, and decoration is elaborate curvilinear rather than simple rectilinear; the forms and character of the ornamentation of the northern European weapons resembles in some respects Roman arms, while in other respects they are peculiar and evidently representative of northern art. The dead were buried in an extended position, whereas in the preceding Bronze Age cremation had been the rule.
In Central Europe, the Iron Age is generally divided in the early Iron Age Hallstatt culture (800–450 BC) and the late Iron Age La Tène culture (beginning in 450 BC). The transition from bronze to iron in Central Europe is exemplified in the great cemetery, discovered in 1846, of Hallstatt, near Gmunden, where the forms of the implements and weapons of the later part of the Bronze Age are imitated in iron. In the Swiss or La Tène group of implements and weapons, the forms are new and the transition complete.
The Celtic culture, or rather Proto-Celtic groups, had expanded to much of Central Europe (Gauls), and, following the Gallic invasion of the Balkans in 279 BC, as far east as central Anatolia (Galatians). In Central Europe, the prehistoric Iron Age ends with the Roman conquest.
From the Hallstatt culture, the Iron Age spreads westwards with the Celtic expansion from the 6th century BC. In Poland, the Iron Age reaches the late Lusatian culture in about the 6th century, followed in some areas by the Pomeranian culture.
The ethnic ascription of many Iron Age cultures has been bitterly contested, as the roots of Germanic, Baltic and Slavic peoples were sought in this area.
Easter Aquhorthies stone circle, located near Inverurie, is one of the best-preserved examples of a recumbent stone circle, and one of the few that still have their full complement of stones. It consists of a ring of nine stones, eight of which are grey granite and one red jasper. Two more grey granite stones flank a recumbent of red granite flecked with crystals and lines of quartz. The circle is particularly notable for its builders' use of polychromy in the stones, with the reddish ones situated on the SSW side and the grey ones opposite.
The placename Aquhorthies derives from a Scottish Gaelic word meaning 'field of prayer', and may indicate a 'long continuity of sanctity' between the Stone or Bronze Age circle builders and their much later Gaelic successors millennia later. The circle's surroundings were landscaped in the late 19th century, and it sits within a small fenced and walled enclosure. A stone dyke, known as a roundel, was built around the circle some time between 1847 and 1866–7.
