Focus on Madonna in Glory with Seraphim (Botticelli) and discuss the History.
The original location of the painting is not known, but it was registered in the Uffizi inventories of 1784 and 1825 as an anonymous artwork. 
The art historian Wilhelm von Bode first attributed it to Botticelli and dated it to the Verrocchio phase of his early career, c. 1469–1470 and just before his Fortitude. Later studies confirmed von Bode's hypothesis, with the exception of Adolfo Venturi who believed it to come from the school of Filippo Lippi.
