In the small frieze on the back wall of the Tomba delle Bighe we find a rider with a led horse, dressed in tunic and helmet, and seated astride; we reproduce part of it after Stackelberg’s water-colour (fig. 21). To the left of him we see a naked man standing on one leg and nursing his raised left leg. It was formerly conjectured that he was playing leap-frog with the young man planting the jumping-pole in the ground behind him, but it is not usual to play leap-frog on one leg, and Weege has pointed out the same position in athletic scenes on Greek vases and supposes it to be a kind of preparatory exercise. His supposition is correct: any modern acrobat would recognize it as one of his exercises; the contraction of the muscles by nursing right and left knee in turn. Acrobats practise this exercise when travelling, to keep themselves fit when they are unable to train. FOOTNOTES: [30] Cp. Fr. Poulsen, _Delphi_, fig. 44. [31] Daremberg-Saglio, _s. v._ _Tutulus_.
