De l'utilité des voyages : et de l'avantage que la recherche des antiquitez procure aux sçavans
A 1686 Paris treatise by Charles-César Baudelot de Dairval arguing the scholarly value of travel and antiquarian collecting, with plates engraved by Franz Ertinger for learned readers. The engravings reproduce coins, medals, engraved gems, lamps and inscriptions as outlined line drawings, giving designers circular and oval frames, standing deities, Latin lettering bent around rims, and isolated small objects on blank grounds.
