Biomechanics. Historical artwork of two humans bearing loads. This illustration is taken from De Motu Animalium (On Animal Motion, 1680) by Alfonso Borelli (1608-1679). The illustration demonstrates how the leg is a twin-lever system controlled by muscles in which the hip (D) and knee (C) are both pivots.
