The Noah figure in this version of the story is named Xisouthros (instead of Zisudra). A god visits him in a dream, warns him that humanity is about to be destroyed in a terrible deluge, and orders him to build a huge boat of the usual dimensions in the usual way. So far this is all very familiar, but then comes a feature not found in the other versions of the tradition. The god tells Xisouthros that he is to gather up a collection of precious tablets inscribed with sacred wisdom and to bury these in a safe place deep underground in 'Sippar, the City of the Sun'. These tablets contained 'all the knowledge that humans had been given by the gods' and Xisouthros was to preserve them so that those men and women who survived the flood would be able to 'relearn all that the gods had previously taught them'.
