Enlightened by impressive chandeliers which are applied in countless small glass lamps,[64] the nave opens into the south portico of the courtyard by a monumental delicately carved wooden door, made in 1828 under the reign of the Husainids.[65] This sumptuous door, which has four leaves richly carved with geometric motifs embossed on the bottom of foliages and interlacing stars, is decorated at the typanum by a stylized vase from which emerge winding stems and leaves.[66] The other doors of the prayer hall, some of which date from the time of the Hafsids,[67] are distinguished by their decoration which consists essentially of geometric patterns (hexagonal, octagonal, rectangular patterns, etc.).[59]
