Lot Essay
A study, in reverse, for Guercino's picture of Saint John the Baptist in the Wilderness, datable to circa 1652-55, formerly in Lord Farnham's Collection (L. Salerno, Il Dipinti del Guercino, Rome, 1988, no. 292). Several examples of Guercino's reversing a composition between drawing and picture exist, for instance the drawing of Jacob blessing the Sons of Joseph in the Art Institute of Chicago (D.M. Stone, op. cit., no. 8), which is in the opposite direction to the painting in Sir Denis Mahon's collection (L. Salerno, op. cit., no. 66).
