Art historian Xavier Salmon suggests that Moulay Isma'il likely donated the anaza at the same time as he restored or added some of the mosque's decoration, although the later may also date from his brother and predecessor, Moulay Rashid (ruled 1666–1672).[9] By comparison, the inner archway of the central northern gate into the courtyard (directly opposite the anaza), has stucco decoration which seems to preserve more of a Marinid style.[9]
