In ancient Egyptian theology, the pylon mirrored the hieroglyph for 'horizon' or akhet, which was a depiction of two hills "between which the sun rose and set." Consequently, it played a critical role in the symbolic architecture of a building which was associated with the place of recreation and rebirth. Pylons were often decorated with scenes emphasizing a king's authority since it was the public face of a building. On the first pylon of the temple of Isis at Philae, the pharaoh is shown slaying his enemies while Isis, Horus and Hathor look on. Other examples of pylons can be seen in Luxor and Edfu.
