Pfortenbuch
The goddesses listed in the "Book of Gates" each have different titles, and wear different coloured clothes, but are identical in all other respects, wearing a five pointed star above their heads. Most of the goddesses are specific to the "Book of Gates", and do not appear elsewhere in Egyptian mythology, and so it has been suggested that the "Book of Gates" originated merely as a system for determining the time at night, with the goddess at each gate being a representation of the main star appearing during the hour.
