In the stylistic development during the Metal Ages, two phenomena are of particular interest. The first is the development of the sun-bird-ship motif of the Urnfield Culture. The origin of this motif, which featured bird-headed ships embellished with solar disks, is not known, but over a short period about 1400 BCE it became common both as incised decoration and as plastic art throughout a vast area of eastern and central Europe. The similarity in execution and composition is remarkable and suggests a shared understanding of its meaning and the intensity of contact between distant areas.
