Sumerian myths and legends of the antediluvian world do much more than speak of the five cities. They also tell an extraordinary story of how their ancestors, who lived in the 'most ancient times', were visited by a brotherhood of semi-divine beings described as half men, half fish, who had been 'sent [by the gods] to teach the arts of civilization to mankind before the Flood' and who had themselves 'emerged from the sea'. The collective name by which these creatures were known was the 'Seven Sages' and the name of their leader was Oannes. Each of them was paired as a 'counsellor' to an antediluvian king and they were renowned for their wisdom in affairs of state and for their skills as architects, builders and engineers.
