Most writers see Campagnola as a professional artist, who received some sort of training in Mantua, Ferrara or Venice. Vasari describes him as a painter, and the Venetian connoisseur Marcantonio Michiel mentions cabinet paintings that were ascribed to him in Venetian collections in about 1530, but no paintings are generally attributed to him, although he is often brought into arguments about the many "Giorgionesque" paintings without an agreed attribution. He is often given a share in the fresco cycle in the Scuola del Santo at Padua, attributed to his son Domenico.
