Neptune (mythology) to. Poseidon on the other hand underwent the process of becoming the main god of the sea at a much earlier time, as is shown in the Iliad. In the earlier times it was the god Portunus or Fortunus who was thanked for naval victories, but Neptune supplanted him in this role by at least the first century BC when Sextus Pompeius called himself "son of Neptune." For a time he was paired with Salacia, the goddess of the salt water. Neptune was also considered the legendary progenitor god of a Latin stock, the Faliscans, who called themselves "Neptunia proles".
Thanatos Thanatos In Greek mythology, Thanatos (; , pronounced in "Death", from θνῄσκω "thnēskō" "to die, be dying") was the personification of death. He was a minor figure in Greek mythology, often referred to but rarely appearing in person. His name is transliterated in Latin as "Thanatus", but his equivalent in Roman mythology is "Mors" or Letum. Mors is sometimes erroneously identified with Orcus, whose Greek equivalent was Horkos, God of the Oath. The Greek poet Hesiod established in his "Theogony" that Thánatos is a son of Nyx (Night) and Erebos (Darkness) and twin of Hypnos (Sleep). Homer also confirmed Hypnos
