Ra is not unique in this relationship with the Eye. Other solar gods may interact in a similar way with the numerous goddesses associated with the Eye. Hathor, a goddess of the sky, the sun, and fertility, is often called the Eye of Ra, and she also has a relationship with Horus, who also has solar connections, that is similar to the relationship between Ra and his Eye. Hathor can even be called "the Eye of Horus"—one of several ways in which the distinctions between the two eyes are blurred. The Eye can also act as an extension of and companion to Atum, a creator god closely associated with Ra. Sometimes this eye is called the Eye of Atum, although at other times the Eye of Ra and the Eye of Atum are distinct, with Ra's Eye the sun and Atum's Eye the moon.
