In art, Nuit was usually depicted as a naked woman with her back arched over the heavens, facing Geb, who lay with his phallus pointed toward her. Often, this image was painted on the inside lid of sarcophagi as a reminder of resurrection. When depicted standing up separately from Geb, she appeared with a water pot on her head (which happened to be the hieroglyph for nuit), and with the colour indigo, representative of the night sky. Sometimes she appeared in the form of a cow whose great body formed the sky and heavens, a sycamore tree, or as a giant sow, suckling many piglets, which represent the stars.
