Rare portrait of the mathematician and Rosicrucian Johann Faulhaber (1580-1635), engraved by Lucas Kilian (1579-1637) in Augsburg. With a numbered list of six published works, with the names of their printers and publishers and the years of publication, 1604-1615. Faulhaber, the official surveyor of the city of Ulm, collaborated with Kepler and was the first to publish the Briggs logarithms in German. His "lasting accomplishment was the dissemination and explanation of the logarithmic method of calculation" (DSB).
Border very slightly shaved, and frayed at the centre of the left edge, torn around the lower right corner of the plate edge. Very good copy of a rare portrait. VD17 23:289362X (1 copy, apparently with the decorative border trimmed off); for Faulhaber: DSB IV, pp. 549-552.
