The second flood was in Achaea, at the time of the patriarchy of Jacob in Judea, and the rule of Ogyges, founder and king of Eleusis, home of the Eleusinian mysteries.
The third flood was in Thessaly, at the time of Moses and king Amphictyon, who reigned first in Thermopylae, and later as the third ruler of Athens after king Cecrops the I, who taught Cecropia (Athens) marriage, reading and writing, and ceremonial burial.
During the third flood, at least to a small extent, the largest part of Thessaly's people managed to reduce their suffering by seeking refuge in the mountains. Especially in Parnassus mountain.
Deucalion, a king in the area, offered them shelter in boats, allowing them to live in the twin Parnassus mountains.
They were treated pretty well, and given chances to begin not just going through life aimlessly, but to also contemplate the world. On account of this event it is also said the people of this Greek story - living with the minerals and stones - had in them sown a "hardened" heart.
