[18] Lit. "if they mount."

[19] Like that of Pheidippides in the play; see Aristoph. "Clouds," 23
foll. And for the price of horses, ranging from 3 minas (= L12
circa) for a common horse, or 12 minas (say L50) for a good saddle
or race-horse, up to the extravagant sum of 13 talents (say 3000
guineas) given for "Bucephalus," see Boeckh, "P. E. A." (Eng. tr.)
p. 74. Cf. Isaeus, 55. 22; 88. 17; Lys. "de Maled." 133. 10; Aul.
Gell. "Noct. Att." v. 2.

To come to the existing body of knights,[20] it would tend,[21] I
think, to better rearing and more careful treatment of their horses if
the senate issued a formal notice that for the future twice the amount
of drill will be required, and that any horse unable to keep up will
be rejected. And so, too, with regard to vicious horses, I should like
to see an edict promulgated to the effect that all such animals will
be rejected. This threat would stimulate the owners of such brutes to
part with them by sale, and, what is more, to exercise discretion at
the time of purchase. So, too, it would be a good thing if the same
threat of rejection were made to include horses that kick on the
exercising-grounds, since it is impossible to keep such animals in the
ranks; and in case of an advance against a hostile force at any
point,[22] they must perforce trail in the rear, so that, thanks to
the vice of the animal which he bestrides, the trooper himself is
rendered useless.

[20] Or, "As regards those who are actually serving in the cavalry."
