Quaternarii Pythagorici

Quaternarii Pythagorici

The Triangle and the Pyramid as the central motif, with the Heavens in a secondary part. From Monas Hieroglyphica.

John Dee, 1564 “Quaternarii Pythagorici.”

John Dee, 1564 “Omnis possibilis Metathesis, 24. Summa Pythagorica, 10. Omnimoda partium additio, dat 30.”

Symbolica, 2026 Dee's Latin, put into English here: Of the Pythagorean Quaternary. Every possible transposition, 24; the Pythagorean sum, 10; the addition of the parts in every way gives 30. The figure is the tetractys of one, two, three and four, whose sum is ten, drawn as arcs rather than as the usual triangle of points, and Dee makes it the arithmetic of his glyph.

The motifs the picture carries, filed by role. The marks on the picture itself come with the entry.
