In the day-time a Greek was usually to be found upon his feet. Of the value of walking as the best of all the more gentle forms of exercise he was well aware, and he normally took a brisk walk in the early morning, another before the mid-day meal, another in the late afternoon, and another before he went to bed. Fortunately for him cycles and motor-cars were not yet invented. When he was not walking he usually stood, for the sitting position was regarded as more appropriate to slaves than to free men, and in any case he knew that sitting tends rather to cramp than to invigorate the body. If he wanted to relieve his leg muscles for a moment, which he seldom did, he dropped down easily into the squatting position, which those other scientific gymnasts, the Japanese, now use, a mode of resting especially valuable for women, as it strengthens all the muscles about the pelvis and gives vigour to the most vital portions of the female anatomy. When the time for a complete rest came he lay down, either propped upon one elbow or at full length, and allowed all his muscles to relax. If ever it was necessary to sit--in the theatre of Dionysus, for example, where an audience sat attentive in the open air for hours together--he sat on a plain flat seat without a back, his legs straight down in front of him, his feet resting on the floor. He did not loll or lounge, and when he was sitting he did not have that round-shouldered appearance, which is now so noticeable in a room full of people: he kept his diaphragm firm with the upper part of his body correctly balanced, the centre of gravity being exactly over the base of the spine; and in this position he was able to remain for long periods without effort or fatigue. But as we have said sitting to a Greek was not a matter of choice, and was for him the exception rather than the rule; he preferred an erect position. The chief reason for this very considerable difference between his custom and ours is to be found in a simple fact: he was taught in childhood how to stand and how to walk _properly_, so that both actions were to him a pleasure and not a labour. It may seem strange at first sight, but as an actual fact the operations of standing erect and walking straight are not in the strict sense of the word ‘natural’ to creatures like ourselves who have painfully evolved from a lower form of life. The awkward hesitations of the baby learning to walk are natural; the supple activity of the athlete is the result of art. To stand gracefully and easily is an accomplishment that must be acquired; it does not come to us of itself.
