KASSIEPEIA Wife to King Kepheus of Aethiopia, Kassiepeia had dared to compare her own beauty to that of the Nereids, and for this temerity the Nereids' protector, Poseidon, visited the land with a terrible flood, and also sent the Kraken to terrorise the citizenry. Kepheus and Kassiepeia were advised by an oracle that the only way that the plague would be lifted from their country was for the rulers to sacrifice their daughter, Andromeda, to the Kraken.
