Eudoxus of Cnidus (/ˈjuːdəksəs/; Ancient Greek: Εὔδοξος ὁ Κνίδιος, Eúdoxos ho Knídios; c. 390 – c. 340 BC) was an ancient Greek astronomer, mathematician, doctor, and lawmaker.[1] He was a student of Archytas and Plato. All of his original works are lost, though some fragments are preserved in Hipparchus' Commentaries on the Phenomena of Aratus and Eudoxus.[2]Spherics by Theodosius of Bithynia may be based on a work by Eudoxus.
