Draughtsman, engraver and publisher, Johan Sadeler I was born in Brussels in 1550. Primarily, he worked as a steel-chiseler or damascener, but later moved to Antwerp where he gained admission to the Guild of St. Luke in 1572 as a copper plate engraver. Sadeler came into contact with members of the Dutch Reformed Church (most likely through Christoph Plantin’s workshop). During his time in Antwerp Sadeler engraved, principally, after the works of Michiel Coxcie and van den Broeck. Sadeler and his brothers collaborated for a number of years with Marten de Vos, (e.g. Jan’s engraving of de Vos’s “Credo”).
