Bast (known as “Bastet” in later times to emphasise that the “t” was to be pronounced) was one of the most popular goddesses of ancient Egypt. She is generally thought of as a cat goddess. However, she originally had the head of a lion or a desert sand-cat and it was not until the New Kingdom that she became exclusively associated with the domesticated cat. However, even then she remained true to her origins and retained her war-like aspect. She personified the playfulness, grace, affection, and cunning of a cat as well as the fierce power of a lioness. She was also worshiped all over Lower Egypt, but her cult was centred on her temple at Bubastis in the eighteenth nome of Lower Egypt (which is now in ruins). Bubastis was the capital of ancient Egypt for a time during the Late Period, and a number of pharaohs included the goddess in their throne names.
