This is a quote from an epic poem by Homer, called Odyssey. It is a citation from the Greek god Zeus. Odyssey is a sequel to an Illiad, and these two poems are essential for the development of modern Western canon. It is believed that the poems were written in 8th Century BC. The poem focuses on Odysseus, king of Ithaca and a hero in the siege of Troy and describes his journey home. It took him 10 years to return home. There is a direct relationship between Zeus and Odysseus, which can be seen through Omens, by which Zeus, god of gods and god of thunder is communicating with Odysseus.
