Geb (formerly erroneously rea as Seb) or Keb (meaning probably: 'lame one', spelled with k-point e.g. once in the Coffin Texts) was i.a. the personification of the earth, amongst the priestly group who believed in the Ennead, a form of Egyptian cosmology centred in Heliopolis, Since the Egyptians held that their underworld was literally that (beside being an abode in and beyond the sky) under the earth, Geb was sometimes seen as containing the dead, or imprisoning those not worthy to go to the heavenly Field of Aaru--reeds.
