Descriptio brevis gemmarum quae in museo Guil. S.R.J.L. Baronis de Crassier, Celsissimi Episcopi ac Principis Leodiensis in Camera Rationaria Consiliarii, &c. asservantur
A Latin catalogue of the engraved gems in Baron Guillaume-Paschal de Crassier's cabinet, printed by Everard Kints at Liège in 1740 for antiquarians and fellow collectors. The plates are small line engravings of intaglios and cameos: laureate and bearded profile heads, double and triple portraits set in oval frames, and one gem mounted in a scrolled pendant setting, all drawn with fine parallel hatching that a designer can lift as medallion portraits, seal shapes, or ornament cartouches.
