Thomae Bartholini De unicornu observationes novae : secunda editione auctiores & emendatiores editae a filio Casparo Bartholino
A 1678 Latin treatise on unicorns by Thomas Bartholin, edited by his son Caspar and printed in Amsterdam by Henricus Wetstein for scholars and naturalists interested in natural history and supposed unicorn horns. The plates are crisp engraved drawings of horns, a sea creature, a serpent and a larva, with fine hatching and clean outlines that suggest early modern scientific specimen illustration.
