The Cavalry General (Hipparchicus)

Written in about 350 BC, the treatises of Xenophon were considered the earliest extant works on horsemanship in any literature until the publication by Bedrich Hrozný in 1931 of a Hittite text, that by Kikkuli of the Mitanni Kingdom, which dates from about 1360 BC. A treatise on horsemanship by Pliny the Elder is believed lost, as was that by Simon of Athens, which is twice mentioned by Xenophon in On horsemanship Hipparchicus deals mainly with the duties of the cavalry commander (hipparchus), while On horsemanship deals with the selection, care and training of horses in general.
