 It is possible that Bonasone learnt of designs of Romano through prints and drawings instead of going to Mantua.The particular technique shared by Bonasone and Scultori could also be developed by each of the two artists independently, since this technique is obtained by formalizing the innovations in Marcantonio Raimondi's prints.Many of Bonasone's works during the 1540s are reproductive works of Roman frescos.
