Sopdet

During the early period of Egyptian civilization, the heliacal rising of the bright star preceded the usual annual flooding of the Nile.

She was long thought to be represented by the cow on an ivory tablet from the reign of Djer (Dynasty I),[8] but this is no longer supported by most Egyptologists.

[9] During the Old Kingdom, she was an important goddess of the annual flood and a psychopomp guiding deceased pharaohs through the Egyptian underworld.

[10] She was depicted as a woman with a five-pointed star upon her head,[10] usually with a horned hedjet similar to Satis.

[10] From the Middle Kingdom, Sopdet sometimes appeared as a god who held up part of Nut (the sky or firmament) with Hathor.

The tablet's engravings were believed to discuss the bull-formed Sopdet.
