Poseidon is the God of the Mediterranean seas, who can strike down His trident and create fresh water springs, or disastrous earthquakes. He is also the Lord of horses, presumably because of the foamy waves rising up like a herd of horses before crashing on the shore. He has made His home underwater, with his wife Amphitrite and other water creatures, many of which immortal. He's a powerful God, one of three brothers who rule the sky, the sea and the underworld.

Claudius Aelianus (Κλαύδιος Αἰλιανός), commonly called Aelian, was born at Praeneste around 175 AD. He was a Roman author and teacher of rhetoric who spoke Greek so perfectly that he was called "honey-tongued" (meliglossos). He preferred Greek authors, and wrote in a slightly archaizing Greek himself. "On the Nature of Animals" (Περὶ Ζῴων Ἰδιότητος) is a collection of seventeen books. All contain brief stories of natural history, sometimes selected with an eye to conveying allegorical moral lessons, sometimes because they are just so astonishing. He also quotes other authors and in the collection, he quotes a hymn to Poseidon I'd like to share with you today. It was originally written by Arion, son of Cycleus, it seems. He wrote the poem in thanks to Poseidon for saving his life. He focusses on dolphins. It goes as follows and probably stems from the fifth century BC:


"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 Nereid maids divine, whom Amphitrite bore, even they that carried me, a wanderer on the Sicilian mean, to the headland of Taenarum in Pelops' land, mounting meupon 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 into the purple swell of ocean."
