Liber desideratus super celestium motuum indagatione sine calculo
Liber desideratus super celestium motuum indagatione sine calculo is an astronomy treatise printed at Cremona by Carolus de Darleriis, with its text attributed to Aegidius and Gulielmus, for scholars of celestial motion and astrological calculation. Its two pictures are square diagrams of the zodiac divided into twelve houses, with signs, planets and degrees written inside the compartments in black letter, useful to a designer for geometric grids, annotated chart layouts and early printed typography.
