Thesaurus gemmarum antiquarum astriferarum : quae e compluribus dactyliothecis selectae aereis tabulis CC insculptae observationibus inlustrantur : adiectis parergis LX, Atlante Farnesiano prolegomenis, diatribis III, dissertationibus XV et indicibus
A 1751 Florentine catalogue of ancient engraved gems, assembled by Gori and Passeri from several cabinets and printed in Florence for antiquarians and collectors of classical art. Its plates are copperplate engravings of gem designs, many with astrological and zodiac motifs, showing figures in oval or round frames within ruled borders. A designer might take their tight oval cameo compositions, crisp line hatching, and classical figure poses as reference for emblems, seals, or antique-style ornament.
