 This dating is made on stylistic and compositional grounds, especially by comparison to the "Saint Ursula".In 1612, the painter Guido Reni left Rome for his native Bologna and on 8 March 1612 gave instructions to the engraver Luca Ciamberlano to collect the remainder of his fees from Reverenda Camera Apostolica for the frescos he had painted in the Borghese Chapel in the Basilica di Santa Maria Maggiore.Ciamberlano again acted on his behalf on 12 September 1612 in the collection of some other debts.
