Nannacus

In Greek mythology, Nannacus was a legendary king of Phrygia before the Flood of Deucalion. His city was Iconium in modern Turkey.

Flood prediction

Nannacus himself had predicted the Flood and had organized public prayers to avert this disaster. These prayers were accompanied by lamentations and from this came the proverbial phrase "weep like Nannacus". The earliest attestation of this proverb is from the third century BC.
According to Stephanus of Byzantium, Nannacus lived three hundred years. There was an oracle that said that when Nannacus died, all his people would perish. Indeed, shortly after the death of Nannacus, the Deluge of Deucalion came and thus the oracle was fulfilled.
At the end of the flood, Prometheus, on the orders of Zeus, again created "images" of people and revived them, from where the name of the place Iconium arose.

Mythological parallels

Also in Asia Minor, the city of Apamea (Phrygia) had boasted of its connection to the Flood. According to James Frazer,
Some scholars have suggested that the patriarch Nannacus was identical to the biblical patriarch Enoch who lived before the flood for three hundred and sixty-five years and was then removed from the world in a mysterious fashion.
