Ariel, meaning the Lion of God or the Hearth of God, has appeared in Coptic, apocry­phal, and mystical Judeo-Christian writings as both an overseer of nature and the regulator of the underworld. Ariel is an archangel takes on the appearance of a fierce and mighty lion, intent on punishing those who succumb to darkness.

Ariel's name being the Lion of God means not that he is ridden with pride that is in association with the lion itself.

The association of Ariel with the spirit of nature was immortalized by Shakespeare, who portrayed this archangel as a tree sprite in The Tempest. In the play, Ariel gains secret knowledge on behalf of the magician Prospero.

Ariel is believed to be a leader of the Virtue choir of angels; those who govern the order of the physical universe, watching over the sun, moon, stars, and all of the planets, including Earth. For this reason, Ariel is intimately involved in environmentalism. Ariel is said to be involved in guiding one into the realm of fairies and other elementals.
