#horfe

They're a little behind the times and still using long S, and all I can see is

Approximately 1345 BCE, Kikkuli, horse-master to the Hittite [the Hittites were some of the earliest "oh my god they have horses and theyre killing everyone" peoples] king Suppililiuma, developed the first recorded plan for training and caring for horses. Many of Kikkuli's training methods are still considered sound and, in their time, they allowed the Hittites to become a mighty power rivaling Egypt.

in the instructions for caring for chariot horses Kikkuli mentions specifically a regimen of rotating exercise and conditioning involving long distance walking and running, which is key to cardiovascular conditioning but also hoof wear and toughening

as for Xenophon, this description of his treatise on horses is funniest when read from "The Hiftory and Art of Horfemanfhip" by Richard Beringer, c. 1720

IN the firft place, we will fhew how any one may be lead liable to impofition in buying an horfe. In a colt that has not yet been broken, it is plain that the Shape mud chiedy be conddered ; for, having never been backed, he can give but very uncertain figns by which to judge his temper. The fil'd part to be attended to is the Foot ; for as an horfe would be of no ufe though the upper parts were very beautiful, if the foundation were inefficient to fupport it; juft fo a war horfe would be good for no¬ thing, how much foever he excelled in all other points, if he had bad feet ; for that alone would difable him from ufmg his other advantages.
