A nice elemental chart
From Einsiedeln, Stiftsbibliothek, Codex 149(558), page 172, a 10th-c. manuscript. Drawn at the very end of Boethius’s Consolation of Philosophy. Here we see the four element, from left to right: Fire (Ignis), Air (Aer), Water (Aqua), and Earth (Terra), with their constituent qualities of dryness (Siccus), heat (Calids*), wetness (Humida), and coldness (Frigida).
- Maybe someone with better Latin & better Paleographical chops than mine can tell me why this is “calids”
