For at a congress of the Lacedaemonian allies and the other Greeks, in which Amyntas, the father of Philip, being entitled to a seat, was represented by a delegate whose vote was absolutely under his control, he joined the other Greeks in voting to help Athens to recover possession of Amphipolis. As proof of this I presented from the public records the resolution of the Greek congress and the names of those who voted.
