Geometria Subterranea is a 1773 German treatise on mine surveying by Johann Gottfried Jugel, published by Kraus, written for students of underground measurement and mining engineering. Its pictures are small black-ink decorative headpieces and tailpieces of scrolling acanthus, flowers, ribbons and shells, drawn in woodcut style on warm paper, offering a designer reference for 18th-century German ornament and vignette borders.
