A kynodesmē (, English translation: "dog tie") was a cord or string or sometimes a leather strip that was worn primarily by athletes in Ancient Greece and Etruria to prevent the exposure of the glans penis in public (considered to be ill-mannered) and to restrict untethered movement of the penis during sporting competition. It was tied tightly around the akroposthion, the most distal, tubular portion of the foreskin that extends beyond the glans. As depicted in Ancient Greek art the kynodesme was worn by some athletes, actors, poets, symposiasts and komasts. It was worn temporarily while in public and could be taken off and put back on at will. The remaining length of cord could either be attached to a waist band to pull the penis upward and expose the scrotum, or tied around the base of the penis and scrotum so that the penis appeared to curl downwards.
