Gorlaeus's Dactyliotheca, a 1601 Delft catalogue of ancient signet rings and their intaglio gems in iron, bronze, silver and gold, compiled by Abraham van Goorle and engraved after designs by Jacob de Gheyn for collectors and antiquarians. The plates show ring bezels beneath engraved cameo roundels, with each ring labelled by metal, stone and number, so a designer can study compact figure scenes and classical motifs within tight circular frames.
