The above ordinance of Lycurgus led in the next instance to the hybernation of the youth upon the mountains:[880] to inure them still further to hardships, and, practically to teach them the art of providing for themselves, they were sent forth with a roving commission to prowl about the highlands and less frequented parts of Laconia, armed for self-protection, and that they might be able to bring down their game. At first, perhaps, they confined themselves within the limits prescribed by law. But almost of necessity they would become involved in quarrels with the Helots, by plundering whose farms and villages they chiefly subsisted. The Helots would sometimes resist and sometimes resent their incursions. Ill blood would be engendered. Hot and fiery youths, abandoned to their own guidance, would easily discover excuses for cruelty and revenge. From quarrels they would proceed to blows—from blows to assassination; and beaten, perhaps, by day, they would fall suddenly on the defenceless peasants in the dead of night, and butcher whole hamlets to avenge an affront offered to them perhaps by an individual. Thus, out of a custom blameless enough in its origin, grew the terrible institution of the Crypteia,[881] or annual massacre of the Helots, denied by some modern writers, but too well authenticated, and too much in keeping with the Spartan character and general policy, to allow of our indulging in any scepticism on the point. Footnote 880: The Platonic Scholiast confounds this practice with the Crypteia, so called, he says, because the youth were compelled to conceal themselves while they subsisted on plunder. Ἀπολύοντες γὰρ ἕκαστον γυμνὸν, προσέταττον ἐνιαυτὸν ὅλον ἔξω ἐν τοῖς ὄρεσι πλανᾶσθαι, καὶ τρέφειν ἑαυτὸν διὰ κλοπῆς, καὶ τῶν τοιούτων, οὕτω δὲ ὥστε μηδενὶ κατάδηλον γενέσθαι· διὸ καὶ κρύπτεια ὠνόμασται· ἐκολάζοντο γὰρ οἱ ὅπου δήποτε ὀφθέντες.—Ad Legg. p. 225. Ruhnk. Footnote 881: For a fuller account of this institution see Book V. Chapter VIII. But, in addition to the above, there were other branches of education taught at Sparta,—that is gymnastics and music. Writers, desirous of enhancing the mental acquisitions of the Dorians, adhere somewhat too strictly to the meaning often affixed by the Greeks to the word _music_, which they employed to signify literature. But Xenophon, in his treatise on the Lacedæmonian Commonwealth, appears invariably to use it in its limited and modern signification.
