De Sphaera

De Sphaera aka Sphaerae coelestis et planetarum descriptio is a collection of astrological plates and diagrams showing the symbolic attributes of the planets, and also their relations in the heavens according to the beliefs of 1470. There’s an obvious similarity to the celebrated (and much imitated) plates from the Splendor Solis (1582) plates although De Sphaera lacks the alchemical dimension of that work. I’ve omitted the diagrams from this post but a facsimile of the entire book may be downloaded from the Biblioteca Estense (see the Collegamenti esterni links here). Wikimedia Commons has some of the plates in better quality.
