Delle porpore e delle materie vestiarie presso gli antichi. Dissertazione epistolare
An 1786 Italian scholarly treatise on Tyrian purple dye and ancient textile materials, written by Michele Arcangelo Giuseppe Rosa as an epistolary dissertation and printed at Modena by the ducal press for learned readers of antiquarian and natural history. Its pictures are small engraved plates: a ruined arch on a shore, a laurelled cameo in ornamental scrollwork, and a sheet of marine snail shells drawn in fine hatched line, offering designers clear models for antique motifs and naturalistic shell study.
