Bat seen in upper left corner of the
Narmer Palette from c. 3100 B.C.
Bat (or Bata) was an old goddess of fertility from Upper Egypt depicted as a cow, woman, or a human face with horns and a cow's ears. Sometimes she was seen with stars like the cow Sopdet. In the Narmer Palette (above) she is seen in the upper corners and her name might be the female form of Ba (the soul).
Pyramid texts say that the deceased king identifies himself with "Bat with her two faces". Her main cult was in Hut-Sekhem, today's Hiw, capital of province six of Upper Egypt whose standard was the sistrum see below), which was Bat's own cultural object. She was also the deification of the Milky Way during the oldest times.
