Etymology
It is borrowed from Ancient Greek ἀστρονομικός (astronomikós, “astronomical”),[1][2] an adjective from the Greek word for astronomy, whose parts are ἄστρον (ástron, “star”) and νόμος (nómos, “custom, law”).[2]
Earliest recorded meaning
Lewis & Short and Georges give the neuter plural Astronomica as the title of Manilius' poem and of a treatise by Hyginus.[3][4] As a common adjective it is first found in Calcidius (c. 300 AD), who speaks of astronomical remedies for the questions he treats.[5][4][2]
Semantic evolution
In Late Latin it qualified the disciplines and reasoning of astronomy, in Boethius and Cassiodorus.[5][4] Medieval Latin used it for both astronomical and astrological matters, and as a noun for an astronomer, for astronomy, and for a book on astronomy.[6][7]
Timeline
- c. 300 AD – Calcidius uses it in his commentary on the Timaeus.[5][4][2]
- c. 485–c. 580 AD – Cassiodorus writes of astronomical rules and matters.[5][2]
