What kind of specialized workers were used in the hanging gardens of Babylon

Some stories indicate the Hanging Gardenstowered hundreds of feet into the air, but archaeologicalexplorations indicate a more modest, but still impressive, height.According to accounts, the gardens were built to cheer upNebuchadnezzar’s homesick wife, Amyitis. Amyitis, daughter of theking of the Medes, was married to Nebuchadnezzar to create analliance between the two nations. The land she came from, though,was green, rugged and mountainous, and she found the flat,sun-baked terrain of Mesopotamia depressing. The king decided torelieve her depression by recreating her homeland through thebuilding of an artificial mountain with rooftop gardens.Babylon rarely received rain and for thegarden to survive, it would have had to been irrigated by usingwater from the nearby Euphrates River. A chain pump had to be made.Wood workers as well as steel workers and mud jars had to be usedin the construction as well as architects and rope makingspecialists.
