Gemmarum affabre sculptarum thesaurus : quem suis sumptibus haud exiguis nec paruo studio collegit Io. Mart. ab Ebermayer Norimbergensis
A Latin catalogue of engraved gems assembled by the Nuremberg collector Johann Martin von Ebermayer and published in Nuremberg in 1720 under the editorship of Johann Jakob Baier, aimed at scholars and collectors of antique gems. Its pictures are small ovals of classical scenes, such as processions, a sacrifice at a temple, and a group of figures around a fallen man, each engraved in fine line with labels naming the gem stones; a designer might take from them the compact oval framing and the crowded, dynamic arrangements of figures in Roman relief.
