Like a number of Alexander the Great‘s companions, we don’t know a lot about Archon. We do know that he died in battle. When Dokimos was given the satrapy of Babylon by Perdikkas, Archon refused to yield. A battle took place between the two and Archon was killed.
Before that, Archon helped navigate the fleet during the Battle of Hydraspes. He also is commemorated for winning several horse races in the Pythian Games and Isthmian Games in 332 and 331 BCE. This is intriguing because Alexander was campaigning in Asia Minor during this time, so you would think Archon wouldn’t have received leave to go play in some games.
Alternatively, Archon only joined Alexander‘s expedition until after he’d won fame. This also seems odd, as Archon was from Pella in Macedonia, so presumably Alexander would have wanted one of his best horsemen in the field. Perhaps we was too young when the expedition left?
Regardless when he joined Alexander, a stele still exists in Delphi that commemorates the life of Archon.
