Mythology Summary
Hapi is the inundation itself - the annual flood of the Nile, not the river - and the fertility it brings, shown as a man with a heavy belly and pendulous breasts, blue or green skinned, carrying produce or pouring water. He lives in a cavern near the First Cataract, his cult was at Elephantine where the nilometer was read, and he is 'lord of the fish and birds of the marshes' and friend of Geb, the earth the silt renews. In the New Kingdom he appears as a pair, Upper and Lower, tying the Two Lands together around the sema symbol.
Modern Practice
Hapi is called at the start of a season, for water on land, and for any work that depends on something arriving from outside. The offering is poured out and the flood is waited for rather than commanded.
