Damask ( ˈda-məsk ) is a fabric with a pattern formed by weaving. The pattern is thus visible on both sides, and often depicts flowers, fruit, forms of animal life, and/or other types of ornament.
Damask originated as the signature fabric of Damascus, the capital city of Syria, where it began being exported to Europe in the Middle Ages.
It remains a popular fabric today, most often used for drapery, upholstery, and table linens.
