From early references it is known that there were works by Jacometto in both Venice and Padua. He was, it seems, chiefly a miniaturist. He works are identified stylistically by comparison with two small portraits in Vaduz. An early report suggests that the figure in Antonello's painting of Saint Jerome either looked like Jacometto or had been repainted by him. There is no justification for believing this, but it shows that Jacometto's work was thought to be closely connected with Antonello.
