Intact sauroter (spear-foot) of big dimensions with tubular socket and pointy end. On the exterior, within a square frame made of dots, inscribed is the letter A.
Sauroters were part of the weaponry used by hoplites. They capped the end opposite to the spearhead as a counterweight and could be used to stand the spear up. If the shaft was broken, then the sauroter could be used as a weapon in its own right. The wooden shaft of the spear would fit into the hollow of the sauroter socket, the aulos.
