Cl. Salmasii De Annis Climactericis Et Antiqua Astrologia Diatribae
A 1648 Latin scholarly treatise on astrology by Claude Saumaise, held by Heidelberg University Library, aimed at antiquarian scholars studying climacteric years and ancient astrology. The four diagrams show a zodiac wheel with Greek-style numerals, a triangular astrological figure set within a zodiac ring, and a tabular grid of planetary and zodiac signs in simple black line on cream paper, offering a designer clean geometric circles, triangles and symbol grids to adapt.
