The ancient city of Babylon, which was under King Nebuchadnezzar II, must have been a wonder to travellers. According to accounts, he built the Hanging Gardens to chirrup his homesick wife, Amyitis. Amyitis was the daughter of the king of the Medes. Where she came from, there was green grass and mountainous plains. She found the dry, flat, sun-baked land of Mesopotamia depressing. The King wanted to recreate her homeland by building an artificial mountain with rooftop gardens. The King Nebuchadnezzar II ruled the city for 43 years starting in 605BC. Ancient accounts say that the hanging gardens have plan its cultivated above ground level and the roots for the tree were embedded in an upper terrace rather than in the earth. Streams of water elevated sources flowed down slopping channels. These water irrigated the whole garden, saturating the roots of plants and keeping the whole area moist. Hence the grass was permanently green and the leaves of trees grew firmly attached to supple branches.
