What does the term arabesque refer?

The arabesque is a form of artistic decoration consisting of "surface decorations based on rhythmic linear patterns of scrolling and interlacing foliage, tendrils" or plain lines, often combined with other elements. It usually consists of a single design which can be 'tiled' or seamlessly repeated as many times as desired. Within the very wide range of Eurasian decorative art that includes motifs matching this basic definition the term "arabesque" is used consistently as a technical term by art historians to describe only elements of the decoration found in two phases: Islamic art from about the 9th century onwards, and European decorative art from the Renaissance onwards. Arabesques are a fundamental element of Islamic art but they develop what was already a long tradition by the coming of Islam. The past and current usage of the term in respect of European art can only be described as confused and inconsistent. Some Western arabesques derive from Islamic art, but others are closely based on Ancient Roman decorations.
