Question

what is the "dreadful oracle" that was delivered to king acrisius?

Answer 1

Answer:

This dreadful oracle was delivered to the ruling king of Argos.

The dreadful oracle was an important element in the story which revealed how he would be killed by his grandchild, ( the king had a daughter who would give birth to a baby boy in the future)

The king was delivered this oracle during the time when his daughter wasn't even married yet. Because of this frightful news and prediction, the king ended up capturing his own daughter. He then gave a command to keep his daughter locked up in a bronze tower so that she could be kept away from men. He wanted that she should never come in front of any man so she would remain unmarried and childless for life. That was the only way he thought would keep himself alive.
