What is "aristomachus"

In Greek mythology, Aristomachus ( Ancient Greek: Ἀριστόμαχος) is a name that may refer to:

• One of the sons of Talaus. He is the father of Hippomedon.
• One of the Heracleidae, son of Cleodaeus, a great-grandson of Heracles. He led an attempt to capture Mycenae during the reign of Tisamenus, but, having misinterpreted the oracle, failed and fell in the battle. He is the father of Temenus, Cresphontes and Aristodemus.
• One of the suitors of Hippodamia before Pelops, was killed by Oenomaus.

Aristomachus was a Byzantine official in Egypt. He was active in the reigns of Tiberius II Constantine (r. 574-582) and Maurice (r. 582-602). He eventually rose to become prefect of Constantinople and "curator domus Augustae" (caretaker of the household of the Augusta), but later fell out of favor and ended his life in exile. The main source about him is John of Nikiû.
