Source Verification: Danaë
Every claim below is either what a named ancient source attests, in its own line or section, or a point where the sources themselves disagree.
What the Sources Attest
Why did Acrisius lock Danaë in a bronze chamber?
An oracle told him that a son born to Danaë would kill him. Acrisius had no son of his own, so he tried to remove the possibility of a grandson entirely by building an underground chamber of bronze and shutting her inside it, sealed away from any man. Zeus was not stopped by the walls, since a god does not need a door.

How did Zeus reach Danaë in the bronze chamber?
He came down through the roof of the chamber as a shower of gold, and she conceived Perseus by him. The image became one of the most repeated in Greek and later Roman art precisely because it makes visible what no lock can stop: a god's approach leaves no broken door and no witness, so Acrisius cannot even prove how it happened.

Why did Acrisius set Danaë and Perseus adrift instead of killing them?
Apollodorus does not give a single stated reason, but the act itself is a common pattern in Greek myth for a king unwilling to kill family directly: casting mother and child into the sea in a sealed chest lets the sea take the blame instead of the king's own hand. Acrisius did not believe Zeus was the father and treated the birth as proof of a human affair, which he punished this way rather than with outright execution.

Where did Danaë and Perseus land after being cast to sea?
Their chest washed ashore on the island of Seriphos, where a fisherman named Diktys found it in his net and raised Perseus. Diktys's brother, King Polydectes, ruled the island and later wanted to marry Danaë; it is Polydectes who sends the grown Perseus after Medusa's head, hoping the quest will kill him and leave Danaë free to marry.

Did the oracle about Acrisius come true?
Yes, though neither man intended it. Years after Perseus and Danaë settled on Seriphos, an adult Perseus competed at funeral games in a distant city where Acrisius happened to be present, and a discus Perseus threw struck and killed him by accident. Perseus did not know his grandfather was in the crowd, which is the detail later authors return to: the oracle is fulfilled exactly, and avoided by no wall or exile.

Where Accounts Differ
- how she reached Seriphos
- Apollodorus gives the fullest connected account of the chamber, the chest, and the landing at Seriphos; later Roman sources (sarcophagi, Horace) treat the shower of gold mainly as an image rather than retelling the surrounding plot.
