Heryshaf (Heri-shef, 'he who is on his lake') is an ancient ram-god whose cult was centered in Middle Egypt at Herakleopolis Magna (now Ihnasiyyah al-Madinah)...
Heryshaf is a fertility god and said to have emerged from the primordial waters. He is depicted as a ram or as a human with a ram's head. His feet rested on earth but his head was in the sky where his right eye was the sun and his left eye was the moon.
Heryshaf is sometimes depicted with four heads.
He is often seen to be the personification of the souls of Osiris and Ra. The Greeks equated Hershef with Herakles.
Chapter 175 of the Book of the Dead associates the lake of Herakleopolis with the blood of Osiris which he lost as the result of an injury incurred by wearing the heavy royal crown. It also explains why blood plays an important role in the rituals of Harsaphes, who had an offering and purification cult near the lake; it is the blood of Seth that poured from his nose when he bowed before Osiris, and which was buried by Re in the ground...
