Sebka () refers to a type of decorative motif used in western Islamic ("Moorish") architecture and Mudéjar architecture.
History and description
Various types of interlacing
rhombus-like motifs are heavily featured on the surfaces of
and other architectural elements in
Morocco and
al-Andalus during the Almohad period (12th–13th centuries). They continued to spread to other decorative mediums such as carved
stucco over the walls of various buildings in Marinid and
Nasrid dynasty architecture, eventually becoming a standard feature in the western Islamic ornamental repertoire, often in combination with
arabesque elements.
George Marçais, a 20th-century scholar on the architecture of the region, said that this motif originated with the complex interlacing arches in the 10th-century extension of the Great Mosque of Cordoba by Al-Hakam II. It was then miniaturized and widened into a repeating net-like pattern that can cover surfaces. This motif, in turn, had many detailed variations. One common version, called darj wa ktaf ("step and shoulder") by Moroccan craftsmen, makes use of alternating straight and curved lines which cross each other on their symmetrical axes, forming a motif that repeats shapes resembling roughly a Hamsa, fleur-de-lis, or palmette. Another version, also commonly found on minarets in alternation with the darj wa ktaf, consists of interlacing Multifoil arch to form a more rounded lobed shape.
