The walls of Greco-Roman Egyptian temples are covered with scenes of offerings. One of the most important offerings in Egyptian temples of the Greco-Roman period is the offering of the two cobras. It shows the king presenting two cobras associated with each other. This article deals with the offering of the two cobras in the mammisi of Philae. It focuses on the scenes and texts of the offering of the two cobras and the purpose of this offering. This study aims to studying the main function of the offering of the two cobras, which appears to express the unification of the two lands and for the king to obtain the rule of all Egypt, i.e. Upper and Lower Egypt, as a legitimate ruler on a united country. This study will be achieved through collecting and translating the texts, identifying the deities, and examining the symbolism and purpose of the ritual.
