Giovanni Antonio da Brescia was an Italian engraver of northern Italy, active in the approximate period 1490–1519, during the Italian Renaissance. In his early career he used the initials "Z.A." to sign some twenty engravings, and until recently Zoan Andrea was regarded as a distinct printmaker; it is now realized that they are the same person, and the "Z.A." stood for Giovanni Antonio, "Zovanni" being a north Italian spelling. Around 1507 he began to use formulae such as "IO.AN.BX.", and signed some prints more fully. The real Zoan Andrea was a very obscure painter, documented as working in Mantua in the 1470s, who produced no engravings.
The newly expanded oeuvre comprises at least 150 engravings, making Giovanni Antonio one of the most prolific Italian engravers of this period. A large number copy other prints, as was then common, and others are probably after drawings by Andrea Mantegna; "all his major works seem to have been based on designs by other artists".
