Transcript of The Hanging Gardens of Babylon

Rebecca Hickey 10A The Hanging Gardens of Babylon The Hanging Gardens are considered the most legendary of the Seven Wonders of the Ancient World. The elusive Hanging Gardens were built by Assyrian king Nebuchadnezzar II in 600 BCE, in Babylon, which is in modern-day Iraq. Some ancient lists of Wonders also featured Babylon's city walls and obelisk attributed to Queen Semiramis. Nebuchadnezzar II was reported to have constructed the gardens to please his homesick wife Amytis of Media, who longed for the plants of her homeland. Screws can be used in two ways; one, as in the case of the Hanging Gardens, is for converting rotating force into upward and downward movement. The other, and more common, usage today is for locking two objects together. SCREW PUMPS were simple machines used in the maintainment of the Hanging Gardens. These were used to lift water up and irrigate the terraced gardens. Experts have estimated that the Hanging Gardens would have required a minimum amount of 8,200 gallons (37,000 liters) of water per day. The Greek inventor was also credited with the invention of the pulley, another simple machine. After the use of screw pumps in Nebuchadnezzar II's Hanging Gardens, no further use of screws had been recorded until Archimedes invented the wooden screw press in 250 BCE. Nebuchadnezzar II was reported to have used massive slabs of stone in the building of the Hanging Gardens, a technique not otherwise attested in Babylon, to prevent the water from eroding the ground. The Hanging Gardens probably did not really "hang" in the sense of being suspended from cables or ropes. The name comes from an inexact translation of the Greek word kremastos or the Latin word pensilis, which mean not just "hanging", but "overhanging" as in the case of a terrace or balcony.
