an engraver on wood, and the supposed inventor of engraving in chiaro- oscuro. Little is known of him or of his works, except a few prints, which are marked with two pilgrims' staves crossed between the initials Jo. V. Among the ten prints mentioned by Bartsch are these: Christ on the Cross, with the Magdalen kneeling at its foot, and the Virgin and St. John standing one on either side; The Virgin, seated in a garden, with the Infant on her knee; The Virgin, half-length, with the Infant in her arms; St. Jerome in the Desert, with a book in one hand and a stone in the other; and St. Sebastian, tied to a tree.
