Al-Malik al-Salih 'Imad al-Din [Abu'l- Fida] Isma'il was the son of al-Malik Nasir al-Din Muhammad Ibn Qalawun. He came to power on 22 Muharram 743 (12 June 1342) and died on 4 Rabi' II 746 (3 August 1345), at the age of twenty (L. A. Mayer, Saracenic Heraldry, Oxford, 1999, pp. 126-7).
This is the only known bowl with the name of Sultan al-Malik al-Salih Isma'il. Wiet writes of a number of other objects which bear his name including the body of a bottle in the Acheroff Collection (M. Gaston Wiet, Catalogue Général du Musée Arabe du Caire, Objets en Cuivre, Cairo, 1982, no.218, p.209), a plate in the Islamic Museum in Cairo (no. 9009, Wiet, op. cit., no. 217, p. 208), a candlestick in the Hariri collection which also bears the name of al-Malik Nasir Muhammad (no.40, Wiet, op. cit., p.10), and a cylindrical box in the Hariri collection (no.119, Wiet, op. cit., p.79).
