A study for figures in the artist's fresco of The Virgin in Glory for the church of Santa Maria della Vita, Bologna. Gaetano worked on decorating the cupola between 1776 and 1779, and it was among the most important commissions of his career. The fresco was surrounded by an elaborate decorative scheme by the quadraturist Serafino Barozzi, with the altar of marble and gilt bronze designed by Pietro Fancelli and Carlo Bianconi. While the fresco has suffered there is a modello for it in the Nelson Atkins Museum of Art, Kansas City (Biagi Maino, op. cit., no. 126, fig. 144). Joshua and Aaron are in the lower left foreground. This sheet was part of an album, dismembered after the 1957 sale which included other chalk studies of similar dimensions by Gaetano for the same church. Of the twelve drawings, eight are known today, and all but the present lot are in museum collections, including The Metropolitan Museum of Art and The Morgan Library in New York, Rhode Island School of Design, and the Ashmolean Museum, Oxford. There are also two preparatory drawings in pen and wash.
