VELTWYCK, GERARD (d. 1555), German Hebraist and apostate. Little is known of Veltwyck's origins or early life. He was for a time the envoy of Emperor Charles V in Constantinople, and the Marrano physician Amatus *Lusitanus, in his book In Dioscoridis… de medics materia… enarrationes (Strasbourg, 1554), mentions that Veltwyck supplied him with medicinal herbs from Turkey.
Veltwyck is mainly remembered for his violently anti-Jewish Hebrew polemical work entitled Shevelei Tohu – Itinera deserti, de Judaicis disciplinis et earum vanitate (Venice, 1539), printed by Daniel *Bomberg. The text, translated into Latin by Conrad *Pellicanus in 1545, forms part of the manuscript (now in Zurich, Zentralbibliothek Ms. Car. 1102) containing Pellicanus' copy of Guillaume *Postel's kabbalistic treatise Or Nerot ha-Menorah (Candelabri typici… interpretatio), which appeared in Venice in 1548. In his Shevilei Tohu – a mixture of verse and prose – Veltwyck revealed his hostility toward the Kabbalah, which he declared to be both devoid of authority and riddled with lies and fancies.
