The centre of ancient Panticapaeum, the capital of the Bosporan kingdom, was adorned by monumental depictions of the kingdom's rulers. One such marble statue, dating from the 4th century B.C., was found on the slopes of Mount Mitridat, the site of the acropolis of Panticapaeum. This may be a depiction of Leucon, one of the Spartocid kings, who ruled in the 4th century B.C. That particular ruler managed to extend the borders of his state almost to the foothills of the Crimean mountains on the Kerch peninsula and to the offshoots of the Northern Caucasus on the Taman peninsula opposite. According to ancient writers, the people of Athens also put up statues to the Bosporan rulers in gratitude for their supplying Attica with grain.
