The Great Flood

The God Vishnu warned Manu of the flood to come.  Manu built a boat to carry his family and with them, the Seven Sages of Antiquity.  Vishnu, who took the form of a large fish, to which the boat was fastened, swam through the great flood and lodged the boat on a mountain peak. 

 

Here Manu, his family and the seven sages remained until the water had subsided and he could safely return.
