Ali ibn Yusuf
More sophisticated illumination is already evident in a copy of a "Sahih" dated to 1120 (during the reign of Ali ibn Yusuf), also produced in either the Maghreb or Al-Andalus, with a rich frontispiece centered around a large medallion formed by an interlacing geometric motif, filled with gold backgrounds and vegetal motifs. A similarly sophisticated Qur'an, dated to 1143 (at the end of Ali ibn Yusuf's reign) and produced in Cordoba, contains a frontispiece with an interlacing geometric motif forming a panel filled with gold and a knotted blue roundel at the middle.
