On Horsemanship is the English title usually given to Περὶ ἱππικῆς, peri hippikēs, one of the two treatises on horsemanship by the Athenian historian and soldier Xenophon (c. 430 – 354 BC). Other common titles for this work are De equis alendis and The Art of Horsemanship. The other work by Xenophon on horsemanship is Ἱππαρχικὸς, hipparchikos, usually known as Hipparchicus, or The cavalry commander. The title De re equestri may refer to either of the two.
On horsemanship deals with the selection, care and training of horses in general. Military training and the duties of the cavalry commander are dealt with in the 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 Bedřich 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. Some fragments of Simon's treatise survive, however; they were published by Ruehl in 1912.
The first printed edition of On horsemanship is that in the complete edition of Xenophon of 1516 from the Giunti press:
The earliest printing in Greek in England may be:
Xenophon details what is to be examined when inspecting a horse to buy as a war-mount. He is especially careful to stress the importance of soundness. His recommendations include:
Xenophon then directs the reader to look at a young colt's cannons to predict his height.
It is interesting to note that many of Xenophon's suggestions are still applied today when selecting a sport horse.
Xenophon first makes a point to say that the reader should not waste his time nor endanger his health by personally breaking colts.
Before the horse is delivered to the trainer, the owner should know that he has a good temperament and gentle nature. The horse should trust people, knowing that they are the providers of food and water. If this is done correctly, the young colt should grow to love people. The groom should stroke or scratch the colt, so that he enjoys human company, and should take the young horse through crowds to accustom him to different sights and noises. If the colt is frightened, the groom should reassure him, rather than punish him, and teach the animal that there is nothing to fear.
