Tratado da sphera : com a theorica do sol & da lua. E ho primeiro liuro da Geographia de Claudio Ptolomeo Alexa[n]drino.
This is a Portuguese treatise on the sphere, astronomy and geography, printed in Lisbon in 1537 by Germão Galharde and built on Sacrobosco, Ptolemy and Pedro Nunes, aimed at navigators and students of the heavens. The pictures are woodcut diagrams: geometric figures with lettered points, a star sphere with its planar projection, and concentric rings showing planetary orbits, giving a designer clean, schematic line work with strong circular and radial structure.
