The study of a scene depicted on the third register of the second chapel of Tutankhamun (1321) helps to identify the nature of the slanting lines projected by six goddesses over the heads of six snakes, each one of them named “wicked of face (ḏwy-ḥr)”. The question is whether these lines refer to water or fire. A contextual analysis of this representation, particularly the name, the characteristics of the snakes, as well as the iconography of the goddesses and the captions attached to them, reveal that these lines represent fire. If the goddesses’ hands spread out flames, this gesture could be explained by the solar light that they represent and project towards the enemies of Re in order to burn them.
