Aelian, Miscellany 4.5
“Democrates the wrestler also had a foot ailment. When he went to a competition he stood in the arena, drew a circle around himself and dared his opponents to drag him over the line. Those who couldn’t, were defeated. He left crowned victor, having stood his ground strongly.”
Δημοκράτης ὁ παλαιστὴς καὶ αὐτὸς νοσήσας τοὺς πόδας, παριὼν εἰς τοὺς ἀγῶνας καὶ στὰς ἐν τῷ σταδίῳ, περιγράφων ἑαυτῷ κύκλον προσέταττε τοῖς ἀντιπαλαισταῖς ἔξω τῆς γραμμῆς αὐτὸν προέλκειν·οἱ δὲ ἡττῶντο ἀδυνατοῦντες. ὁ δὲ εὖ διαβὰς ἐν τῇ στάσει καὶ ἐγκρατῶς, στεφανούμενος ἀπῄει

From Brill’s New Pauly, s.v. Democrates
 Attic orator of the 4th cent. BC from Aphidna
Attic orator of the 4th cent. BC from Aphidna, probably an older contemporary of Demosthenes  (about 338 BC he is called γέρων (gérōn; old man), cf. Stob. Floril. 3,22,43). As the descendant of Harmodius or Aristogeiton, he had a claim to free provisions in the Prytaneion (Hyp. 4,3). He belonged to the Pro-Macedonian party (Hyp. 4,2). He is also mentioned in Aeschin. Leg. 2,17 and Isaeus 6,22.
