NEPTUNE, NEPTUNUS. Neptune, the Roman sea god, was identified with the Greek Poseidon, lord of the sea, of earthquakes, and of horses. Neptune and Apollo helped King Lamedon build the walls of Troy; then the king refused to pay them as he had agreed and thus earned their hatred (Met XI.199-215).
Neptunus is the god of the sea, FranklT 1047; Tr II.443. Phebus and Neptunus are angry with Troy because King Lameadoun did not pay them their wages, Tr IV.120-124. Neptune has compassion on Demophon and tosses him, almost dead, on the beach of Rhodopeya, LGW 2421-2438. [Demophon: Phebus]
Neptune, the English variant, with silent final -e, occurs once, in medial position, LGW 2421. Neptunus, the Latin form, occurs three times in medial positions, FranklT 1047; Tr II.443, IV.120.
