The litmus test. Saint Francis lying on the embers
Ca. 1787. Oil on canvas.On display elsewhere
It is part of the series of thirty-three scenes from the Life of Saint Francis (Assisi, Italy, 1182-1226) painted for the basilica of San Francisco el Grande in Madrid. The painters José Camarón y Bonanat (1731-1803), Antonio Carnicero (1748-1814) and Manuel de la Cruz (1750-1792) were involved in this cycle, which belongs entirely to the Museo del Prado.
This scene, commissioned to its author for the decoration of the lower cloister, represents how while in Egypt, St. Francis is tempted by a beautiful woman, whom he rejects by submitting himself to the sacrifice of lying on an enormous brazier from which he emerged unharmed. Before this vision, the woman, repentant, converted to the faith of Christ.
