A Dictionary of Greek and Roman biography and mythology

2. Of the demos of Paeania in Attica, was a son of Demosthenes's sister, and distinguished himself as an orator; he belonged, like his great kinsman, to the anti-Macedonian party. When, after the death of Alexander, Demosthenes was still in exile and tried to rouse the Greeks to a vigorous resistance against the Macedonians, Demon proposed a decree to recall him. It was joyfully passed by the Athenians, and Demosthenes returned in triumph. (Plut. Dem. 27 ; Athen. 8.341, xiii. p. 593, where a son of his, Phrynion, is mentioned.)
