Philip Pouncey pointed out that this is a preparatory drawing for one of Salimbeni's most important commissions outside Siena, the vault of the chapel of San Massimo in Santa Maria degli Angeli, Assisi, P.A. Reidl, Zum Oeuvre des Ventura Salimbeni, Mitteilungen des Kunsthistorischen Institutes in Florenz, 1959-60, IX, p. 225, pl. 4. Salimbeni worked on the commission for three frescoes of the life of Saint Clare in 1599 after his return from Rome. An earlier compositional study of the subject is in the Albertina (no. 411). Preparatory studies for the other frescoes are at Chatsworth (no. 377), Windsor (A.E. Popham and J. Wilde, The Italian Drawings of the XV and XVI Centuries in the Collection of His Majesty the King at Windsor Castle, London, 1949, no. 997 as attributed to Vanni) and Florence, P.A. Riedl, op. cit., 1976, no. 90, fig. 89. The additional figures pasted onto this drawing may suggest a knowledge of Barocci's preparatory studies such as the study of the Madonna del Popolo from from Chatsworth sold in these Rooms, 6 July 1987, lot 2.
