Lot Essay
The composition is related to the altarpiece executed by Guercino in 1634 and now in the Musée Granet in Aix-en-Provence (Turner, op. cit., no. 205, ill.). The painting, representing Christ appearing to Saint Teresa and showing her the glory of God, is recorded in Guercino’s Libro dei conti (B. Ghelfi, Il libro dei conti del Guercino, 1629-1666, Venice, 1997, pp. 72-73 and 75) as commissioned by Barthélémy Lumague for his family chapel in Lyon. A print after the painting was executed by Gilles Rousselet (1610-1686) and many preparatory drawings for the composition survive (Turner, op. cit., p. 493, under no. 205). In all the literature cited above this drawing is given to Guercino himself. Of the connected drawings, it is the closest in composition to the painting, but it is unusual in the use of red chalk.
