easy one ! :) Acrisius' grandson was sent out to kill him unless he killed his daughter. But the gods would punish you if you killed family.
To go kill him self under a rock or a cave
King Acrisius died when his grandson Perseus accidentally hit him with a discus.
In the end, Acrisius dies at the hands of his grandson Perseus during a discus-throwing competition. This fulfills the prophecy that his daughter Danaë's son would kill him, as he tried to prevent Perseus from becoming the king of Argos.
Because an oracle told him his grandson would one day kill him and take his throne
When Acrisius consulted the Pythia regarding his chances for having a son, he was told that he would never have a son of his own, but rather, his daughter would. Further, that grandson would eventually kill him. This is why he locked Danae in the tower away from men, to prevent her from having that child. That son would be Perseus, who did indeed kill Acrisius after slaying Medusa.
Acrisius was killed in Larissa, by Perseus. As it was foretold by an oracle that Acrisius's daughter Danae, would have a child that would one day kill him - who turned out to be Perseus
Her name was Danae, daughter of King Acrisius of Argos. The oracle had told Acrisius that his grandson would kill him, so he imprisoned Danae in an underground chamber without a roof. Zeus came to her as a shower of liquid gold, and impregnated her. Years later, her son Perseus was playing at discus when the wind caused his discus to veer, striking Acrisius in the head and killing him.
King Acrisius locked Danae in a tower because the Oracole of Apollo told him a son of Danae would kill him, so therefor he did not want her to have any children
I don't know of a the king you mentioned, but if you are referring to the mythical Greek king of Argos King Acrisius than he died when his grandson Perseus accidentally hit him and killed him with a discus fulfilling the prophecy. He had even been warned by an oracle that his daughter Danaë's son would kill him.
This sory starts with King Acrisius, who is afraid of getting a grandson by his daughter Danae. She is visited by Zeus and gives birth to Perseus. Acrisius puts these two in an old boat on the Mediterranean, hoping the will drown. Eventually they find themselves in the palace of King Polydectes, who wants to get rid of Perseus (now a grown man) in order to woo Danae. So he sends Perseus on a misson to kill Medusa, the terrible monster. and so on.
Perseus was not sent away by his father, but by his grandfather Acrisius. Acrisius had a daughter named Danaë, and when he heard a prophecy that he would die by the hand of Danaë's son, he desperately tried to avoid his fate. Acrisius locked Danaë up in a room that was completely sealed, apart from a hole in the roof through which she could breath and be fed. He thought he was safe, but the god Zeus spotted the lonesome Danaë and payed her a visit, and then fathered her child, Perseus. When Acrisius heard of Perseus, he intended to kill the child, but when he learned that his grandson was a demigod son of Zeus, he dared not do so. Instead he sent Danaë and Perseus away to sea in a chest, saying that their drowning would be the fault of Poseidon.
