<p style='text-align: justify;'>This Venetian edition of Peuerbach's <i>Theoricae novae </i>was copied from Apian's 1528 edition, printed in Ingolstadt. Subsequently, the work went through several further editions. Apian's edition added new woodcuts as well as notations to some of those from earlier editions. Some errors in the woodcuts in the 1528 edition were repeated in this Venetian edition of 1537. This diagram cannot be found in the original set which appeared in Regiomontanus's edition of Peuerbach's <i>Theoricae novae planetarum</i> (c. 1474), but was added to the initial series after a diagram on stations and retrogradations. Using the example of the Moon, it shows that planets are sometimes 'diminished' in light, as they are in speed.</p>
