Lycurgus (16.5-16.6)

The boy who excelled in judgement and was most courageous in fighting, was made captain of his company; on him the rest all kept their eyes, obeying his orders, and submitting to his punishments, so that their boyish training was a practice of obedience. Besides, the elderly men used to watch their sports, and by ever and anon egging them on to mimic battles and disputes, learned accurately how each one of them was naturally disposed when it was a question of boldness and aggressiveness in their struggles.

Of reading and writing, they learned only enough to serve their turn; all the rest of their training was calculated to make them obey commands well, endure hardships, and conquer in battle. Therefore, as they grew in age, their bodily exercise was increased; their heads were close-clipped, and they were accustomed to going bare-foot, and to playing for the most part without clothes. When they were twelve years old, they no longer had tunics to wear, received one cloak a year, had hard, dry flesh, and knew little of baths and ointments; only on certain days of the year, and few at that, did they indulge in such amenities.
