Plant-based scrolls were very widely used in Greek and Roman architectural decoration, spreading from them to other types of objects. They may have first evolved in Greek painted pottery, where their development can traced in the large surviving "corpus". In Europe Greco-Roman decoration, probably especially as seen in jewellery and floor mosaics, was adapted by the "barbarian" peoples of the Migration Period into interlace styles, often replacing the plant forms of the main scrolling stem with stretched and stylized animal forms. In Anglo-Saxon art the interlace designs of the early pagan Anglo-Saxons were partly replaced by vine scrolls after Christianization, and medieval European decoration in general evolved styles that combined the two.
