A solar deity (also sun god/dess) is a sky deity who represents the Sun, or an aspect of it, usually by its perceived power and strength. Solar deities and sun worship can be found throughout most of recorded history in various forms.

The sun is the bestower of light and life to the totality of the cosmos; with his unblinking, all-seeing eye, he is the stern guarantor of justice; with the almost universal connection of light with enlightenment or illumination, the sun is the source of wisdom.
