Description
Paulus continued his father’s efforts to propagate classical scholarship, as with this work concerning the accurate representation of the three-dimensional heavens in the two dimensions of a sundial. The original Greek text of the Analemma of Claudius Ptolemy (ca. 90–ca. 168 CE) does not survive, and this edition is based on a Latin manuscript discovered and edited by Federico Commandino (1509–1575). Commandino appended to this edition his own work on the construction of sundials.
