Oryktographia Hildesheimensis : sive, admirandorum fossilium, quae in tractu Hildesheimensi reperiuntur, descriptio iconibus illustrata, cui addita sunt alia de calculis de fontibus, &c.
Oryktographia Hildesheimensis is a 1669 Latin natural history catalogue of fossils found near Hildesheim, written by Friedrich Lachmund and printed there for its author. The illustration shows numbered woodcut plates of irregular stone forms, drawn in dense parallel hatching and cross-hatching that models their rounded, lumpy surfaces, with a small black-and-white scale bar at lower right, offering a designer a clear example of early engraved line shading for organic shapes.
