Note 301 — Chapter IX · DEMOSTHENES
Reading edition
The last private speeches of which the genuineness is undoubted are dated about 346 and 345 B.C., but others, e.g. Against Phormio, of which the authenticity was not questioned in ancient times, go down to 326 B.C. or even later. The genuineness of the Phormio is at least probable.
