As to warfare, as in the _Tain Bo Cualgne_, the Irish romance based on the manners of the late Celtic period (200 B.C. to 200 A.D.), the gentry fight from chariots, dismounting at will, while the host, with spears, or with slings, bows and arrows, follows or exercises its artillery from the flanks. Except when the rain of arrows does execution, we hear next to nothing of the plebeian infantry. The age of hoplites was as remote as the age of cavalry, and the phalanxes are only mentioned when they are broken. The chariot age is familiar in Assyrian, Egyptian, and Minoan art, as among the Britons and Caledonians who fought with Rome. The chariot was extremely light; a man could lift a chariot and carry it away (_Iliad_ x. 505). Probably the chariot came into use for war, as Mr. Ridgeway supposes, in an age when a pony was unequal to the weight of a man in armour; the Highlanders, with their Celtic ponies, used chariots in Roman times; never did they acquire a breed of horses fit for chargers, hence they lost the battle of Harlaw. To judge by Homer’s description of horses, the chariot survived the cause of its origin; steeds were tall and strong enough for cavalry purposes, but human conservatism retained the chariot. A speech of Nestor, in _Iliad_, Book iv. 303-9, shows that Homer knew by tradition the Egyptian custom of charging in serried squadrons of chariotry, while in his own day the lords of chariots usually fought dismounted, and in the loosest order, or no order. Nestor naturally prefers ‘the old way’; no late poet could have made this interpolation, for, in the Greek age of cavalry, he could have known nothing of chariotry tactics. The Egyptian chariotry used the bow, while their adversaries, the Khita charioteers, fought with spears, in loose order, as in Homer--and had the worst of the fight. The Homeric retention of the huge body-covering shield, familiar in Minoan art, was more or less of a survival of a time when archery was all-important. The shield, as among the Iroquois and in mediaeval Europe, was suspended by a belt. The same shields, among the Red Indians, and in the Middle Ages (eleventh and twelfth centuries), were, so to speak, umbrellas against a rain of arrows; as the bow became more and more despised, the historic Greeks adopted the round parrying buckler, good against spear- and sword-strokes. The body armour, as far as greaves are concerned, was an advance on Minoan practice. In Minoan art the warriors are usually naked under the huge shields; happily, one or two seals found in Crete, and a pair of greaves in Cyprus, prove that greaves, cuirass, _zoster_, and _mitrê_, the mailed kirtle of Homer, were not unknown even before the earliest age at which one could venture to place the Epic (see Note).
