The violent form of the Eye was also invoked in religious ritual and symbolism as an agent of protection. The uraeus on royal and divine headdresses alludes to the role of the Eye goddesses as protectors of gods and kings. For similar reasons, uraei appear in rows atop shrines and other structures, surrounding and symbolically guarding them against hostile powers. Many temple rituals called upon Eye goddesses to defend the temple precinct or the resident deity. Often, the texts of such rituals specifically mention a set of four defensive uraei. These uraei are sometimes identified with various combinations of goddesses associated with the Eye, but they can also be seen as manifestations of "Hathor of the Four Faces", whose protection of the solar barque is extended in these rituals to specific places on earth.
