Many of the devices are curious by which this indifference to life has been matured and sustained. In ancient Athens the public temples were closed to those who refused military service, who deserted their ranks or lost their bucklers; whilst a law of Charondas of Catana constrained such offenders to sit for three days in the public forum dressed in the garments of women. Many a Spartan mother would stab her son who came back alive from a defeat; and such a man, if he escaped his mother, was debarred not only from public offices but from marriage; exposed to the blows of all who chose to strike him; compelled to dress in mean clothing, and to wear his beard negligently trimmed. And in the same way a Norse soldier who fled, or lost his shield, or received a wound in any save the front part of his body, was by law prevented from ever afterwards appearing in public.[281] There are, indeed, few military customs but have their origin and explanation in the artificial promotion of courage in the minds of the combatants. This is true even to the details and peculiarities of costume. English children are, perhaps, still taught that French soldiers wear red trousers in order that the sight of blood may not frighten them in war-time; and doubtless French children imbibe a similar theory regarding the red coats of the English. The same reason was given by Julius Ferretus in the middle of the sixteenth century for the short red frock then generally worn by the military.[282] The first mention of red as a special military colour in England is said to have been the order issued in 1526 for the coats of all yeomen of the household to be of red cloth.[283] But the colour goes, at least, as far back as Lycurgus, the Spartan lawgiver, who chose it, according to Xenophon, because red is most easily taken by cloth and most lasting; according to Plutarch, that its brightness might help to raise the spirits of its wearers; or, according to Ælian and Valerius Maximus, in order to conceal the sight of blood, that raw soldiers might not be dispirited and the enemy proportionately encouraged. The bear-skin hats, which still make some English regiments so ridiculous and unsightly, were originally no doubt intended to inspire terror. Evelyn, writing of the year 1678, says: ‘Now were brought into service a new sort of soldiers called Grenadiers, who were dexterous in flinging hand-grenades, every man having a handful. They had furred caps with coped crowns like Janizaries, which made them look very fierce; and some had long hoods hanging down behind as we picture fools.’ We may fairly identify the motive of such headgear with the result; and the more so since the looking fierce with the borrowed skins of bears was a well-known artifice of the ancient Romans. Thus Vegetius speaks of helmets as covered with bear-skins in order to terrify the enemy,[284] and Virgil has a significant description of a warrior as Horridus in jaculis et pelle Libystidis ursæ.
