Note 734 — Chapter LXXXVIII · EUBOIC AND OLYNTHIAN WARS.
Reading edition
Æschines indeed says, that Kallias, having been forgiven by Athens on this occasion, afterwards, gratuitously and from pure hostility and ingratitude to Athens, went to Philip. But I think this is probably an exaggeration. The orator is making a strong point against Kallias, who afterwards became connected with Demosthenes, and rendered considerable service to Athens in Eubœa.
The treason of Kallias and Taurosthenes is alluded to by Deinarchus in his harangue against Demosthenes, s. 45.
