Caravaggio’s life in Milan played out in contiguous neighbourhoods. The residence-workshop of Merisi’s maestro, Simone Peterzano, was in the parish of San Giorgio al Pozzo Bianco. Michelangelo lived and worked there from fourteen to eighteen years of age. The recent identification of more mature drawings by the young apprentice permit the claim that the temporal terms of the contract were respected and that Caravaggio did not withdraw from his obligation prior to the agreed date.
