The arabesque is the rhythmic linear ornament of interlacing stems, leaves, and tendrils that became one of the defining languages of Islamic art, developing from the vegetal scroll mosaics of the Umayyad period and reaching classical refinement across the medieval and early modern Islamic world. Its endless, self-repeating growth - in both vegetal and strictly geometric varieties - has been read as an image of infinite divine order, generated by hidden geometry beneath the organic surface. The term is European ('arabesque' in the French ornament tradition), and the vocabulary was absorbed into Renaissance and 19th-century European design, while the word itself acquired other lives, from ballet's poised leg line to a genre of literary fantasia.

Defining characteristics
Continuous scrolling stems and tendrils that never terminate - the pattern reads as infinite
Split-palmette leaves, half-leaves, and buds alternating along a rhythmic line
Symmetry and rotational repetition: mirror, glide, and two- or four-fold repeats
Strict figure-ground interplay in which ground and ornament hold equal weight
Geometry beneath the organic surface: grids and radii generate the curves
