The Greeks were too sensible and too well aware of the importance of securing true body poise to deprive of its vitality that part of the body which is the chief factor in balance, as being the main point of contact between ourselves and the solid ground. As a result the Greek foot was in some important respects differently shaped from ours. The first three toes were longer and were thin and nervous like fingers; the second toe was often the longest of the three; the fourth and fifth toes were little used and were usually off the ground, being thus raised by a pad of firm fleshy tissue, spreading under the foot, on which all movement centred. The instep was not quite so high as with us, but the tendon Achilles was finer, the heel considerably smaller and much less used, for a Greek child was trained to dispense with it as a security for balance and to keep the centre of gravity over the forward part of the foot. All these points of difference are perfectly well known to modern artists and can be observed in most ancient statues. It rests with ourselves, if we wish it, to recover the combination of beauty and strength which the Greek foot possessed; and if the attempt be made it will be found that it is not impossible even for us soon to approach with some closeness to that desirable ideal. Let us suppose then for a moment that our feet are sensibly shod and that their muscles are properly exercised: let us suppose also that we have learned enough of the principles of body poise and balance to be able to ‘stand at ease.’ With the next order ‘Quick march!’ a new series of difficulties will begin. Correct walking requires that the centre of gravity of a moving weight should be kept constant over its base, and to do this the muscles must be in a state of elastic tension. If the diaphragm is not doing its work, the act of passing the weight of the body from one foot to another results in an effort to feel forward for a new base, and movement proceeds in jerks. The way to avoid this jerky movement is to carry the whole weight forward at the same time as the advancing foot, and this can only be done if mind and muscle work together. The essential difference between a soldier’s march, if it be properly performed, and the civilian’s walk, degenerating into a slouch, is that the first calls for a definite mental effort; the second is mere mechanical habit. As soon as men march mechanically they cease to march, and that is the value of a regimental band: it stimulates the connection between mind and muscle that centres round our diaphragm.
