Giovanni Bazzi was born in Vercelli, Piedmont, in 1477. His first master was the "archaic" Martino Spanzotti; he also appears to have been a student of the painter Giovenone. After acquiring the strong colouring and other distinctive stylistic features of the Lombard school and – though he is not known to have travelled to Milan – somehow absorbing the superficial mannerisms of Leonardo (Freedberg 1993:117), he travelled to Siena before 1503, perhaps at the behest of agents of the Spannocchi family, and began with fresco cycles for Olivetan monks and a series of small Ovidian ceiling panels and a frieze depicting the career of Julius Caesar for Sigismondo Chigi at Palazzo Chigi.
