The groom must also know about putting the muzzle on the horse when he takes him out to be groomed or to the rolling-place. In fact he must always put the muzzle on when he leads him anywhere without a bridle.The muzzle appears on several Greek vases. The Greek horse was given to biting. For the muzzle prevents him from biting without hampering his breathing; and moreover, when it is put on, it goes far towards preventing any propensity to mischief.
5.4
He should tie up the horse at a place above the head, because when anything irritates his face, the horse instinctively tries to get rid of it by tossing his head upwards; and if he is tied thus he loosens the halter instead of breaking it by tossing up his head.
5.5
In rubbing the horse down, the man should start at the head and mane; for if the upper parts are not clean, it is idle to clean his lower parts. Next, going over the rest of his body, he should make the hair stand up with all the dressing instruments,The instructions are rather vague. and get the dust out by rubbing him the way the hair lies. But he should not touch the hair on the backbone with any instrument; he should rub and smooth it down with the hands the way it naturally grows; for so he will be least likely to injure the rider’s seat.
5.6
He must wash the head well with water, for, as it is bony, to clean it with iron or wood would hurt the horse. He must also wet the forelock, for this tuft of hair, even if pretty long, does not obstruct his sight, but drives from his eyes anything that worries them; and we must presume that the gods have given the horse this hair in lieu of the long ears that they have given to asses and mules as a protection to their eyes.
5.7
He should also wash the tail and mane, for growth of the tail is to be encouraged in order that the horse may be able to reach as far as possible and drive away anything that worries him, and growth of the mane in order to give the rider as good a hold as possible.
