CharybdisÂ was a sea monster in Greek mythology. In the beginning, Charybdis was a woman, daughter of Poseidon and Gaia, a great thief famous for her voracity.One day she stole the bulls of Geryon from Heracles, she ate a few of them. Zeus got mad and struck her with lightning so that she fell into the sea, he there turned her into a monster, with the shape of a whirlpool.
This monster was able to swallow all the ships that passed by. Charybdis was placed where we today find the harbour of Messina, on the other side of the Strait of Messina there was the monster Scylla. All the ships had to pass by close toeither of these two monsters. There are indeedÂ whirlpools in the Strait of Messina because sea currents, but not very relevant.
Legend has it that only the Argonauts (a band of heroes) managed to get by without losing their lives to one of these monsters, thanks to the protection of Thetis, mother of Achilles and one of the Nereids.
