Known under various names (Nu, Neph, Cenubis, Amen-Kneph,
Khery-Bakef), Ptah is the creator god and god of craftsmen.
He is usually depicted as wearing a closely fitting robe
with only his hands free. His most distinctive features are
the invariable skull-cap exposing only his face and ears,
and the _was_ or rod of domination which he holds,
consisting of a staff surmounted by the _ankh_ symbol of
life. He is otherwise symbolized by his sacred animal, the
bull.
