Painter, draughtsman, architect and artistic adviser, son of Daniel Heintz.
He began his training as a painter c. 1579 with Hans Bock I (c. 1550-c. 1623) in Basle. His first surviving drawings (1580) show something akin to Holbein manner in his stained-glass window designs. After completing his apprenticeship he went c. 1584 to Rome, where he studied the works of antiquity, and those of Raphael, Michelangelo, Polidoro da Caravaggio and others. In 1587 he went via Florence to Venice, absorbing the works of Tintoretto, Titian and Veronese. In autumn 1591 the Holy Roman Emperor Rudolf II summoned him as portraitist and court painter to Prague but soon sent him back to Italy, where he drew ancient statues in addition to producing his own work and acting as art agent for the Emperor. In 1592-5 he stayed mainly in Rome, then returned to Prague. In the following years he worked indefatigably as a draughtsman, painter, architect and artistic adviser, moving between Augsburg and Prague.
