After his family was ruined by the Sack of Prague in the Thirty Years' War, the young Hollar, who had been destined for the legal profession, decided to become an artist. The earliest of his works that have come down to us are dated 1625 and 1626; they are small plates, and one of them is a copy of a "Virgin and Child" by Dürer, whose influence upon Hollar's work was always great. In 1627 he was in Frankfurt where he was apprenticed to the renowned engraver Matthäus Merian. In 1630 he lived in Strasbourg, Mainz and Koblenz, where Hollar portrayed the towns, castles, and landscapes of the Middle Rhine Valley. In 1633 he moved to Cologne.
