Note 2368 — BOOK IX. THE NATURAL HISTORY OF FISHES.
John Bostock translation
Appian tells us, B. v., that Sextus Pompeius, on gaining some successes against Augustus at sea, caused himself to be called the “Son of Neptune,” as having been adopted by that divinity. There is also a coin of Pompey extant, which attests that he adopted the surname of “Neptunius.”
