Quotations
The horse was not in the least like a Greek horse (nor even a Trojan), and F.M. the Duke of Wellington was not represented with the ensis or short sword in his grasp, the chlamys flying from his shoulder, or the paludamentum, as more suitable for the cool of the English climate (totidem divisos orbe &c.), the kothornos on his leg, the galea slung at the crupper? no reins, and his naked nether-man, not (as in these precious models) seated on the bare back of the bull-necked, square-jawed, dray-limbed steed.
