(Θεόχρηστος), of Cyrene, grandfather and grandson, won a victory at the Olympic games in the chariot-race, but in what Olympiad is not stated (Paus. 6.12.7). A person of the same name is quoted by the Scholiast on Apollonius Rhodius (4.1750) as the author of a work on Libya; and from the subject of the book we may reasonably infer that he was a native of Africa, and may have been the same as one of the Olympic victors. Pliny also refers to Theochrestus as one of his authorities. (H. N. Index, lib. xxxvii. and 37.2. s. 11.1.)
