Note 565 — Chapter LXXXVII · FROM THE COMMENCEMENT OF THE SACRED WAR TO THAT OF THE OLYNTHIAN WAR.

These and other details are given in Plutarch’s Life of Demosthenes, c. 4, 9. They depend upon good evidence; for he cites Demetrius the Phalerean, who heard them himself from Demosthenes in the latter years of his life. The subterranean chamber where Demosthenes practised, was shown at Athens even in the time of Plutarch.

Cicero (who also refers to Demetrius Phalereus), De Divinat. ii. 46, 96. Libanius, Zosimus, and Photius, give generally the same statements, with some variations.
