The Aleppo school was a workshop tradition of Christian icon painting founded by the priest Yusuf al-Musawwir (Joseph the Painter) and active in Aleppo from at least 1645 to 1777. Its atelier drew on the icon tradition of Crete - long a hub where Eastern and Western Christian representations intermingled - and adapted it to the churches of Ottoman Aleppo. The school's best-known work is the Last Judgement fresco painted by Nehmatallah Hovsep in 1703 in the Armenian Cathedral of the Forty Martyrs. Its icons stand at the meeting point of the Byzantine icon and Westernizing post-Renaissance painting: hieratic saints, densely populated judgement scenes and hagiographic cycles rendered with Cretan-inflected modelling, ornament and architecture.
