Danae in Greek and Roman Biography and Mythology
（Δανάη). See ACRISIUS. We may add here the story which we
meet with at a later time in Italy, and according to which
Danae went to Italy, built the town of Ardea, and married
Pilumnus, by whom she became the mother of Daunus, the
ancestor of Turnus. (Verg. A. 7.372, 409, with Servius's
note.) - A Dictionary of Greek and Roman biography and
mythology, William Smith, Ed.
Danae in Wikipedia
In Greek mythology, Danae (Ancient Greek: Δανάη, English
translation: "parched") was a daughter of
King Acrisius of Argos and Eurydice (no relation to Orpheus'
Eurydice). She was the mother of Perseus by Zeus. She was
sometimes credited with founding the city of Ardea in
Disappointed by his lack of male heirs, Acrisius asked an
oracle if this would change. The oracle told him to go to
the Earth's end where he would be killed by his daughter's
son. She was childless and, meaning to keep her so, he shut
her up in a bronze tower or cave. But Zeus came to her in
the form of golden rain, and impregnated her. Soon after,
their child Perseus was born.
None too happy, but unwilling to provoke the wrath of the
gods by killing his offspring, Acrisius cast the two into
the sea in a wooden chest. The sea was calmed by Poseidon
and at the request of Zeus the pair survived. They washed
ashore on the island of Seriphos, where they were taken in
by Dictys - the brother of King Polydectes - who raised the
boy to manhood.
Later, after Perseus killed Medusa and rescued Andromeda,
the oracle's prophecy came true.
He started for Argos, but learning of the prophecy instead
went to Larissa, where athletic games were being held. By
chance, an aging Acrisius was there and Perseus accidentally
struck him on the head with his javelin (or discus),
fulfilling the prophecy. Too shamed to return to Argos he
then gave the kingdom to Megapenthes, son of Proetus
(Acrisius's brother) and took over his kingdom of Tiryns,
also founding Mycenae and Midea there.
Another version states that, angry that his grandfather
tried to kill him and his mother, Perseus returned home and
challenged Acrisius in his court. He took out Medusa's head
from a sack and turned Acrisius and his court to stone. -
