BOETIUS-ADAM, an eminent engraver, born at Bolswert in Friesland, about the year 1580; died in 1634. It is inferred, from his style, that he studied in the school of Bloemaert. His principal works are the following:—after Rubens, "The Last Supper," "Resurrection of Lazarus," "The Crucifixion," and "The Judgment of Solomon;" "The Martyrdom of St Stephen," after Coninghoo; "Jesus with Martha and Mary," after Gesmian; after Bloemaert, "The Adoration of the Shepherds," "The Holy Women in the Desert," in twenty plates, four landscapes, and twenty landscapes inscribed O minium felix, 1616. Bolswert was also the author of a romance entitled The Pilgrimage to Jerusalem.

or BOLWERT, SCHELTIUS, the younger brother of the preceding, lived at Antwerp about the middle of the seventeenth century, and has left admirable prints after some of the finest works of Rubens and Vandyck. He worked entirely with the burin, and without stippling. His finest works are—the "Christ crowned with Thorns," after Vandyck; "The Assumption," "The Brazen Serpent," "Mercury and Argus" and two prints of Satyrs, after Jordans; "A Lion Hunt," after Rubens; and a "Crucifixion."
