Nasrid art was influenced by the cultural and geographical diversity of Islamic civilisation. As such, a unique synthesis of vegetal, geometric and calligraphic motifs is what characterises its creative output, regardless of medium. Moreover the common inclusion of the Nasrid motto wa la ghaliba illa Allah or ‘Only God is the Victorious’ became a trademark of the art of this period. Inscriptions from the Quran, notable poetry and simple expressions such as al-afiyah or ‘Good Health’ are also expressed through exquisite kufic and naskh calligraphy.
The main component of Nasrid plasterwork is gypsum (hydrated calcium sulphate). Retardants such as salts, glue or calcium carbonate were added to slow the setting and permit carving while panels were still damp. Sometimes the back would be reinforced with a rougher gypsum plaster containing sand and fibres. On the samples taken from the mortars, only gypsum was found. As a retardant, salts or glue may have been used. No trace of calcium carbonate was found.
