The Persian bow, according to Herodotus and Xenophon, was of unusual size. According to the sculptures, it was rather short, certainly not exceeding four feet. It seems to have been carried strung, either on the left shoulder, with the arm passed through it, or in a bow-case slung at the left side. It was considerably bent in the middle, and had the ends slightly turned back. [PLATE XXX., Fig. 1.] The arrows, which were of reed, tipped with metal, and feathered, were carried in a quiver, which hung at the back near the left shoulder. To judge from the sculptures, their length must have been about two feet and a half. The arrow-heads, which were either of bronze or iron, seem to have been of various shapes, the most common closely resembling the arrow-heads of the Assyrians. [PLATE XXX., Fig. 3.] [Illustration: PLATE XXX.] Other offensive weapons carried occasionally by the Persian foot-men were, a battle-axe, a sling, and a knife. The battle-axe, which appears in the sculptures only in one or two instances, is declared to have been a common Persian weapon by Xenophon, who, upon such a point, would seem to be trustworthy. The use of the sling by the Persian light-armed is quite certain. It is mentioned by Curtius and Strabo, no less than by Xenophon; and the last-named writer speaks with full knowledge on the subject, for he witnessed the effect of the weapon in the hands of Persian slingers during his return with the Ten Thousand. The only missiles which the Persian slingers threw were stones; they did not, like the Rhodians, make use of small lumps of lead. The knife seems also to have been a Persian weapon. Its blade appears to have been slightly curved, like that of a pruning-hook. It was worn in a sheath, and was probably thrust into the belt or girdle like the similar weapon, half knife, half dagger, of a modern Persian. The ordinary defence of the Persian against the weapons of his enemy was a shield of wicker-work, which covered him almost from head to foot, and which probably differed little from the wattled shield of the Assyrians. [PLATE XXX., Fig. 2.] This he commonly planted on the ground, supporting it, perhaps, with a crutch, while he shot his arrows from behind it. Occasionally, he added to this defence the protection of a coat of mail, composed either of scale armor, or of quilted linen, like the corselets of the Egyptians. Armor of the former kind was almost impenetrable, since the scales were of metal--iron, bronze, or sometimes gold--and overlapped one another like those of a fish.
