According to Allen, the first usage of the name "Bellatrix" for this star was in the Alfonsine Tables published in Spain in 1252 under the patronage of King Alfonso X of Leon and Castile. This name represents a very free translation of the Arabic name for this star, Al Najid meaning "The Conqueror".
