To the bow and sling were soon added spears, swords, axes, and javelins, all of which appear to have been used by the Jews. David destroyed Goliath with a stone from the brook. The invention of the sling is attributed, by ancient writers, to the Phœnicians, or the inhabitants of the Balearic Islands. The great fame that these islanders obtained arose from their assiduity in its use; their children were not allowed to eat until they struck their food from the top of a pole with a stone from a sling. From the accounts left us (probably fabulous), it appears that the immense force with which a stone could be projected, can only be exceeded by modern gunnery. Even at that early age, leaden balls were in use as projectiles; though we cannot put much faith in Seneca’s account of the velocity being so great as frequently to melt the lead. The use of the sling continued over a long period of time, even as late as the Huguenot war in 1572. The bow is of equal, if not greater, antiquity. The first account we find of it is in Genesis, 21st chapter and 20th verse, where the Lawgiver, speaking of Ishmael, says, “And God was with the lad, and he grew and dwelt in the wilderness, and became an archer.” The arms of the ancient Greeks and Persians were such as we have described, with the addition of chariots armed with scythes, in which the chiefs sometimes fought; though their main dependence was upon their heavy-armed infantry. Elephants were afterwards used as adjuncts in their military operations, but their use does not appear to have been very great or very permanent. The Romans were armed much in the same manner as the Greeks, with a slight difference in the form of their weapons; and the arms of the early Saxons were similar; those of the Normans were only altered in their construction, except that to them appears to be awarded the invention of the _cross-bow_, an instrument which afterwards became of great repute in England and elsewhere. It has also been asserted, that the Normans were the first to introduce a species of field artillery, from which stones and darts were thrown, and arrows, headed with combustible matter, for firing towns and shipping. The artillery-proper of the ancients, as the engines for projecting masses of stone and such like materials may be termed, reached to wonderful perfection; and the velocity with which missiles of every description could be thrown from them, attest the skill and ingenuity exercised in their construction: indeed it is quite evident they are only excelled by the _more portable_, and simply constructed, artillery of our own day. The great artillerist of the Sicilians, Archimedes, seems to have made some of the most powerful engines; but he, considering any attention to mechanics as beneath the philosopher, has not left us an account of any one of them.
