When shown as a lioness, she is associated with sunlight.
She was the goddess of many things including fire, cats, dance,
sex, music, and good luck. According to one myth, she was the personification
of the soul of Isis. She was also called the "Lady of the East".
As such, her counterpart as "Lady of the West" was Sekhmet.
Her
counterpart, Sekhmet, the powerful one, was called into being by
Re, the Sun god, to punish humanity for plotting rebellion. Her
lioness nature enjoyed the bloody mission so much that she could
not be stopped. The gods, fearing that humanity would be destroyed
altogether, had their servants prepare seven thousand jars of beer
laced with red dye. They spread it on the fields, and upon waking
she drank it all, thinking it was blood. The beer so addled her
that she returned to her place to sleep it off, and mankind was
saved. Both Bastet and Sekhmet are parts of the single creative
force of the universe. The feminine force not only creates life,
but it takes it away. (Statue and text are housed in the Field Museum,
Chicago, Illinois.)
The fist cat whose name we know of was Nedjem - it means star.
