Bastet was a goddess in ancient Egyptian religion, worshiped as early as the 2nd Dynasty (2890 BC). As Bast, she was the goddess of warfare in Lower Egypt, the Nile River delta region, before the unification of the cultures of ancient Egypt. Her name is also translated as Baast, Ubaste, and Baset. In Greek mythology, she is also known as Ailuros.
The uniting Egyptian cultures had deities that shared similar roles and usually the same imagery. In Upper Egypt,Sekhmet was the parallel warrior lioness deity. Often similar deities merged into one with the unification, but that did not occur with these deities having such strong roots in their cultures. Instead, these goddesses began to diverge. During the22nd Dynasty (c. 945–715 BC), Bast had transformed from a lioness warrior deity into a major protector deity represented as a cat. Bastet, the name associated with this later identity, is the name commonly used by scholars today to refer to this deity.
