File talk:1550 SACROBOSCO Tractatus de Sphaera - (16) Ex Libris rare - Mario Taddei .JPG

The figure is not from Sacrobosco
In his Tractatus de Sphaera, Sacrobosco does not discuss the planetary models -- especially not in the specific detail depicted here. I note that the legends to the diagrams are in italian, while the description gives the Italian title: "Annotazione sopra la Lettione della Spera del Sacrobosco". Could we get a more accurate description of this figure? --SteveMcCluskey (talk) 22:17, 16 December 2010 (UTC)
