Poseidon, Shaker of the Earth

I begin to sing about Poseidon, the great god, mover of the earth and fruitless sea, god of the deep who is also lord of Helicon and wide Aegae. A two-fold office the gods allotted you, O Shaker of the Earth, to be a tamer of horses and a saviour of ships! Hail, Poseidon, Holder of the Earth, dark-haired lord! O blessed one, be kindly in heart and help those who voyage in ships! Homeric Hymns XXII
