"And the day wore on, and still Olney listened to rumours of old times and far places, and heard how the Kings of Atlantis fought with the slippery blasphemies that wriggled out of rifts in ocean’s floor, and how the pillared and weedy temple of Poseidonis is still glimpsed at midnight by lost ships, who know by its sight that they are lost."
"Trident-bearing Neptune was there, and sportive tritons and fantastic nereids, and upon dolphins’ backs was balanced a vast crenulate shell wherein rode the grey and awful form of primal Nodens, Lord of the Great Abyss."
H.P. Lovecraft, The Strange High House In the Mist
"The symbol of Poseidon's power was the trident, or a spear with three points, with which he used to shatter rocks, to call forth or subdue storms, to shake the earth, and the like."
"His figure does not present the majestic calm which characterises his brother Zeus; but as the state of the sea is varying, so also is the god represented sometimes in violent agitation, and sometimes in a state of repose. It must be observed that the Romans identified Poseidon with their own Neptunus, and that accordingly the attributes belonging to the former are constantly transferred by the Latin poets to the latter."
William Smith, Dictionary Of Greek and Roman Biography and Mythology
"Highest of the gods, lord of the sea, Poseidon of the golden trident, earth-shaker in the swelling brine, around thee the finny monsters in a ring swim and dance, with nimble flingings of their feet leaping lightly, snub-nosed hounds with bristling neck, swift runners, music-loving dolphins, sea-nurslings of the Nereis (Nereid) maids divine, whom Amphitrite bore, even they that carried me, a wanderer on the Sikelian main, to the headland of Tainarion in Pelops' land, mounting me upon their humped backs as they clove the furrow of Nereus' plain, a path untrodden, when deceitful men had cast me from their sea-faring hollow ship in to the purple swell of sea."
Aelian, On Animals
