"The Epic of Gilgamesh", who was an ancient Sumerian king (c. 3000 BC), is our first detailed written evidence of human civilization. In a Victorian translation of a Gilgamesh variant, Leonidas Le Cenci Hamilton's Epic of Ishtar and Izdubar, King Izdubar sees "a mass of colors like the rainbow’s hues" that are "linked to divine sanction for war." Later in the epic, Izdubar sees the "glistening colors of the rainbow rise" in the fountain of life next to Elam’s Tree of Immortality.
