As Amun's cult grew bigger, Amun rapidly became identified with the chief God that was worshipped in other areas, Ra-Herakhty, the merged identities of Ra, and Horus. This identification led to a merger of identities, with Amun becoming Amun-Ra. As Ra had been the father of Shu, and Tefnut, and the remainder of the Ennead, so Amun-Ra was likewise identified as their father. Ra-Herakhty had been a sun god, and so this became true of Amun-Ra as well, Amun becoming considered the hidden aspect of the sun (e.g. during the night), in contrast to Ra-Herakhty as the visible aspect, since Amun clearly meant the one who is hidden. This complexity over the sun led to a gradual movement towards the support of a more pure form of deity.
