2nd century AD; precise identity and dates disputed. Wrote in Greek. Author of the lost anti-Christian polemic The True Word ("Alethes Logos"), known today only through Origen's point-by-point rebuttal, Against Celsus. Ancient and modern scholars disagree on whether this Celsus should be identified with an Epicurean philosopher of the same name mentioned elsewhere by Lucian -- a live, unresolved question rather than a settled fact, worth flagging honestly rather than assuming the identification.
