De astronomia
De astronomia (Latin: [deː äs̠t̪rɔˈnɔmiä]; Concerning Astronomy) is a book of stories written in Latin, probably during the reign of Augustus (c. 27 BC – AD 14). Attributed to "Hyginus", the text describes 47 of the 48 Ptolemaic constellations, centering primarily on the Greek and Roman mythology surrounding the constellations, though there is some discussion of the relative positions of stars.
