Socrates Chrestus: A Bithynian Prince in the Context of Roman and Pontic Politics

Introduction

Socrates Chrestus was a prince of the Nicomidean dynasty of Bithynia, active in the decade after the death of his father Nicomedes III (c. 94–90 BC) and recorded as dead between 90 and 88 BC. He was the second son of Nicomedes III by a concubine named Hagne; his father sent Hagne and the boy to Cyzicus with 500 talents. His elder half brother, Nicomedes IV, was recognized by the Roman senate as king after Nicomedes III’s death.

Socrates came to power not by regular succession but through Pontic intervention. Mithridates VI of Pontus received Socrates with honors, gave him a military force and set him up in opposition to Nicomedes IV; contemporary historians describe Socrates as reluctant to claim the throne yet placed on it by Mithridates. Socrates went to Rome seeking official recognition, which the senate refused. Rome then supported the restoration of Nicomedes IV, dispatching Manius Aquillius (with support from Cassius, who raised troops in Galatia and Phrygia) to enforce the decision; Livy’s summary and other sources record Nicomedes IV’s restoration by 88–90 BC.

After his deposition Socrates appears in the sources as an exile. Granius Licinianus reports that he returned to Cyzicus, murdered his sister and fled to Euboea where a Roman eques named Cornelius hosted him. Justin gives a different account, stating that Mithridates arranged his murder. Ancient testimonies therefore disagree on whether Socrates died by Pontic action or survived briefly in exile. His historical footprint is limited to these episodes of Pontic interference in Bithynia and the Roman response during the prelude to the Mithridatic conflicts.
