Aristolaos, a Macedonian, dedicated the statue of Ptolemy, the son of Ptolemy Lagus. There is also set up a statue of Boutas, son of Polyneikes, a Milesian, who gained victory in boxing among the boys. Kallikrates from Magnesia on the Lethaios is also represented there, who won two crowns in the race in armor; the statue of Kallikrates is the work of Lysippos.
