Pordenone, Il Pordenone in Italian, is the byname of Giovanni Antonio de’ Sacchis, an Italian Mannerist painter, loosely of the Venetian school. Vasari, his main biographer, wrongly identifies him as Giovanni Antonio Licinio. He painted in several cities in northern Italy "with speed, vigor, and deliberate coarseness of expression and execution—intended to shock".
He appears to have visited Rome, and learnt from its High Renaissance masterpieces, but lacked a good training in anatomical drawing. Like Polidoro da Caravaggio, he was one of the artists often commissioned to paint the exteriors of buildings; of such work at most a shadow survives after centuries of weather. Michelangelo is said to have approved of one palace facade in 1527; it is now only known from a preparatory drawing. Much of his work was lost when the Doge's Palace in Venice was largely destroyed by fires in 1574 and 1577. A number of fresco cycles survive, for example part of one at Cremona Cathedral, where his Passion scenes have a violence hardly repeated until Goya.
