Jan was in Antwerp by 1572; it was then the centre of the printmaking world, with hugely productive workshops producing work for publishers with excellent distribution arrangements throughout Europe. In that year he became a master of the artists'
Guild of Saint Luke, and married in
Antwerp Cathedral. By 1569 or 1570, he was working for the publisher
Christopher Plantin. His younger brother Rafael I joined him there, and they continued to work closely together, moving to
Cologne in about 1579, but continuing to visit Antwerp. The disruptions of the
Dutch Revolt scattered all the Antwerp artists across Northern Europe, and after the siege of Antwerp in 1585 Jan and Rafael worked in several German cities -
Mainz, Frankfurt-am-main, and Munich without settling for long, before they went to Italy in 1593, where Jan may have died. They first went, accompanied by their nephew Aegidius II, to
Verona, then
Venice from 1596/7, where they had a shop. In 1604 Rafael returned to Munich, where he remained for most of the rest of his life, of which the last record came in 1622. Jan's son Marcus, or Marco, remained in Italy as a publisher and artist, though there may be confusion between his work and that of his presumed relation the older Marcus. Three of their best-known prints after the Bassani are known as the "Sadeler kitchen scenes". They show respectively Christ in the house of Mary and Martha, at
Emmaus, and
Dives and Lazarus. Jan’s testament, drafted on 17 August 1600 and today in the Archivio di Stato in Venice, gave specific instructions to his son Justus for the administration of both his family and business and, among other things, required him to compile an inventory of the copperplates in the shop. Long believed lost, the inventory of the Venetian printing shop as drawn up on 20 November 1600 has recently resurfaced in the Archivio di Stato di Venezia. It reveals that upon Jan’s death the Sadeler shop contained 475 copperplates; 368 of which were the sole property of Jan, with the remaining 107 jointly owned by Jan and his brother Aegidius. The stock was dispersed after the death of Jan’s heir, Justus, in 1620 File:Jan Sadeler Hochzeit von Peleus und Thetis.jpg|The
