From Plutarch’s Sayings of Kings and Commanders (Frank Cole Babbitt trans.); Antigonus was considered one of Alexander the Nice’s successors:
When Marsyas his brother had a lawsuit, and claimed the proper to have the trial held at his home, Antigonus mentioned, ‘It shall be within the Discussion board and with everyone listening to see whether or not we do any injustice.’
