This is a detail from Rembrant's great work taken from Greek mythology. Danae is generally portrayed in her locked room as Zeus arrives in the form of a shower of gold. Their offspring was Perseus. Danae was locked away by her father, Acrisius, because the oracle had foretold that her son would kill him. When he discovered the union of Zeus and Danae, Acrisius locked her and her son in a chest that was set adrift. Eventually, they were rescued on the shore of Seriphus. With the change in venue, came a change in the outcome. Instead of killing his grandfather, Perseus killed King Polydectes of Seriphus, who tried to force himself on Danae. Now, does this painting make any more sense?
In 1985 this painting was viciously slashed and bathed in acid by a deranged man. The restoration proved highly successful.
