 The English word "antelope" first appeared in 1417 and is derived from the Old French "antelop", itself derived from Medieval Latin "ant(h)alopus", which in turn comes from the Byzantine Greek word "anthólops", first attested in Eustathius of Antioch (), according to whom it was a fabulous animal "haunting the banks of the Euphrates, very savage, hard to catch and having long, saw-like horns capable of cutting down trees".It perhaps derives from Greek "anthos" (flower) and "ops" (eye), perhaps meaning "beautiful eye" or alluding to the animals' long eyelashes.This, however, may be a later folk etymology.
