An ancient dictum says that when Zeus wanted to destroy someone, he would first drive him mad.
Bear up, my child, bear up; Zeus who oversees and directs all things is still mighty in heaven.
Basically, Apollo was more of a mediator between Zeus in Olympus and Perseus on Earth. He played much more of an active role.
For know that no one is free, except Zeus.
It is not possible either to trick or escape the mind of Zeus.
