Cassiopeia (mother of Andromeda)

Her origins are obscure. Nonnus calls her a nymph,[2] while according to Stephanus, she was called Iope, the daughter of Aeolus, from whom the town of Joppa (now the Jaffa neighborhood in Tel Aviv) derived its name.[3]

Cassiopeia boasted that she (or her daughter Andromeda), was more beautiful than all the Nereids, the nymph-daughters of the sea god Nereus. This brought the wrath of Poseidon, ruling god of the sea, upon the kingdom of Ethiopia.[4]

Accounts differ as to whether Poseidon decided to flood the whole country[5] or direct the sea monster Cetus to destroy it. In either case, trying to save their kingdom, Cepheus and Cassiopeia consulted a wise oracle, who told them that the only way to appease the sea gods was to sacrifice their daughter.

Accordingly, Andromeda was chained to a rock at the sea's edge and left to be killed by the sea monster. Perseus arrived and instead killed Cetus, saved Andromeda and married her.[5]

Poseidon thought Cassiopeia should not escape punishment, so he placed her in the heavens chained to a throne in a position that referenced Andromeda's ordeal. The constellation resembles the chair that originally represented an instrument of torture. Cassiopeia is not always represented tied to the chair in torment; in some later drawings she holds a mirror, symbol of her vanity, while in others she holds a palm frond.[6][7][8]

The constellation Cassiopeia, near to the pole star, can be seen from latitudes north of 35°N during the whole year. The constellation is also visible in countries north of the Tropic of Capricorn, in late spring.

According to the 1922 regnal list of Ethiopia, Cassiopeia (known as Kasiyope) ruled Ethiopia as part of the Agdazyan dynasty and reigned for 19 years from 1890 to 1871 BC, with dates following the Ethiopian calendar.[9]
