Tefnut is known to the Egyptians as Sekhmet, the furious form of the immensely famous Bastet, the peaceful and protective cat-headed deity.
From her hieroglyphic presentation as the standing goddess wearing the royal sun, the linear will greatly simplify to keep only an evocation of the limbs and a horizontal line.

She is assigned by Rà the mission of embodying the soft and creative humidity, the morning dew, the water suspended in the air, in a mirror of Shou which is the hot air.
