An important work, the catalogue of the collection of the Duc de Croy. Jacob de Bie (1581–1650), Mintmaster at Brussels from 1612 to 1613, was also a well-known historian and the author of several major numismatic works. While the 1615 first edition is generally attributed to him, Hemelaer is accorded primary authorship by Dekesel for this seldom-offered second edition. Over a century later, an Amsterdam edition revised by Ludolph Smids and Sigebert Havercamp was published utilizing the same plates. Banduri (1719) 50–51. Brückmann (1729) 55. Dekesel H70. Hirsch 60.
