Aristion (died 86 BC in
Athens) was a
philosopher and
tyrant of Athens from 88 BC to 86 BC. Aristion joined forces with
Mithridates against the Romans under
Lucius Cornelius Sulla in the
First Mithridatic war, but to no avail. On March 1, 86 BC, Athens was conquered by Sulla and Aristion was executed. He is called
Athenion by
Posidonius, and he may be the same person, or he may be a second tyrant whose story became confused with the first.
