Levni's pictorial narrative of the Surname-i Vehbi poet Vehbi's account of the festival organized in 1720 to commemorate the circumcision of four sons of Sultan Ahmed III is undoubtedly one of the masterpieces of Ottoman art and possibly the last great example of illustrated Islamic manuscript. Preserved in the Topkapı Palace Museum in İstanbul the work is illustrated with 137 paintings that re-create the personages settings and events of an extraordinarily lively and enchanting age known as the Tulip Period.
