Phil Weimerskirch, a very good librarian friend, sent this piece. He has found me some fantastic material.

Spanheim, Ezechiel. Dissertationes de praestantia et usu numismatum antiquorum. Edition secunda, priori longe auctior, & variorum numismatum. Amstelodami: Apud Danielem Elsevirium, 1671. 4to (20.9 cm, 8.25"). Frontis., [46], 917, [51 (index)] pp.; illus.

Important treatise on ancient numismatics, written by a prominent scholar, diplomat, and collector who was one of the first to combine genuine interest in coins and medals with antiquarian erudition. This is the second edition, following the first of 1664 but more highly illustrated than that printing; the volume includes numerous in-text copper engravings depicting coins and monuments, at least one of which is signed I. Wyngaerden. The title-page is printed in red and black, with Elzevir's Minerva vignette.
