Deiochus

(Δηΐοχος), of Proconnesus, is mentioned by Dionysius of Halicarnassus (Jud. de Thuc. 2, 5) as one of the earliest Greek historians, who lived previous to the time of Herodotus. He is probably the same person as the Deiochas whom Stephanus of Byzantium (s. v. Λάμψακος) calls a native of Cyzicus, and who wrote a work on Cyzicus (περὶ Κυζίκου), which is frequently referred to by the Scholiast on Apollonius Rhodius, who, however, calls him by his proper name only once (on 1.139), and in all the other passages refers to him under the name of Δηίλοχος, or Διίοχος. (Schol. ad Apollon. 1.961, 966, 976, 987, 989, 1037, 1062, 1063, 1065, 2.85, 106.) [L.S]
