This enameled and gilded mosque lamp on a high foot is decorated with six circular blazons of a red cup on a white field, the heraldic symbol of a cupbearer in the service of the Mamluk Sultan al-Nasir Nasir al-Din Muhammad during the last of his three reigns (1310–1340). The patron would have been either Baktamur al-Muʿazzami or Qawsun al-Nasiri, both of whom served the sultan during this period. Sultan al-Nasir’s name is inscribed in three roundels on the underside of the body. The lotus flower decoration and shape of the lamp support its dating to the years between 1320 and 1340.
