Gemmarum et lapidum historia.
This is a 1636 Latin treatise on gems and stones by Anselmus de Boodt, edited by Adrianus Tollius and printed at Leiden for scholars and naturalists. Its woodcut plates show carefully drawn mineral and fossil specimens: a pair of tubular pieces labelled A, B and C, a tapering stone with a drilled hole, a cone-shaped object with a bored hole, and a coiled ammonite-like shell rendered in fine parallel hatching, offering designers clear, contour-led studies of natural forms.
