Benben was the mound that arose from the primordial waters Nu upon which the creator god Atum settled in the creation story of the Heliopolitan creation myth form of Ancient Egyptian religion.
In Egyptian mythology, the obelisk symbolized the sun god Ra, and during the religious reformation of Akhenaten it was said to have been a petrified ray of the Aten, the sundisk. The earliest temple obelisk still in its original position is the 68-foot (20.7 m) 120- metric-ton (130- short-ton) red granite Obelisk of Senusret I of the Twelfth Dynasty at Al-Matariyyah in modern Heliopolis.
