warrior of Hirschlanden, and the statue from the Glauberg, Germany. Hallstatt artists in the early Iron Age favored geometric, abstract designs perhaps influenced by trade links with the Classical world. The more elaborate and curvilinear La Tène style developed in Europe in the later Iron Age from a centre in the Rhine valley but it soon spread across the continent. The rich chieftain classes appear to have encouraged ostentation and Classical influences such as bronze drinking vessels attest to a new fashion for wine drinking. Communal eating and drinking were an important part of Celtic society and culture and much of their art was often expressed through plates, knives, cauldrons and cups. Horse tack and weaponry were also decorated. Mythical animals were a common motif along with religious and natural subjects and their depiction is a mix between the naturalistic and the stylized. Megalithic art was still sometimes practiced, examples include the carved limestone pillars of the sanctuary at Entremont in modern-day France. Personal adornment included torc necklaces whilst the introduction of coinage provided a further opportunity for artistic expression. The coins of this period are derivatives of Greek and Roman types, but showing the more exuberant Celtic artistic style. The famous late 4th century BCE Waldalgesheim chariot burial in the Rhineland produced many fine examples of La Tène art including a bronze flagon and bronze plaques with repoussé human figures. Many pieces had curvy, organic styles though to be derived from Classical tendril patterns. In much of western Europe elements of this artistic style can be discerned surviving in the art and architecture of the Roman colonies. In particular in Britain and Ireland there is a tenuous continuity through the Roman period, enabling Celtic motifs to resurface with new vigour in the Christian Insular art from the 6th century onwards. The sophisticated Etruscan culture developed from the 9th to 2nd centuries, with considerable influence from the Greeks, before finally being absorbed by the Romans. By the end of the period they had developed writing, but early Etruscan art can be called prehistoric. Africa Ancient Egypt falls outside the scope of this article; it had a close relationship with the Sudan in particular, known in this period as Nubia, where there were advanced cultures from the 4th millennium BCE, such as the "A-Group", "C-Group", and the Kingdom of Kush.
