Erwin Straus, The Upright Posture
The legs support the body like columns; in the hip joint, the trunk rests upon the femur bones as upon pillars. At least, it seems to. The appearance is convincing enough for a hysterical person to use it as a model for his astasia-abasia. If one tries, however, to carry through the comparison in detail, one sees immediately the striking contrast to the architectonic principles of column and pillar. Many old temples have collapsed, leaving their columns still standing erect. The stone pillars of a bridge are constructed from the foundation upward. Each lower section really carries the upper one, which can be removed without unbalancing the lower ones. Neither the skeleton nor the legs will stand of their own power. The legs could not do it, even if the muscles could still contract and were not severed from their origin on the pelvis. The legs have to be held in suspension by the counteraction of the trunk muscles and by the counterweight of the trunk. A column, a pillar, a tower, taper off. Their bases are broader than the top. Human legs also have a conical shape, but the bulk is high. The origin of the muscles, and therefore their main volume, is on top. The muscles extend with their tendons downward from pelvis to knee and again from knee to ankle. Their contraction, however, is directed upward.
