The event that shows that the ancient Greeks valued intelligence in Perseus is when Athena gives Perseus a mirror so he does not look directly at Medusa.
Answer: Option D
<u>Explanation:</u>
Perseus as a custom would give a gift for the bride to be. Here Perseus promised that he would go and kill Medusa and bring her head as the gift. It was a task unaccomplished because Medusa was one of the Gorgons.
Athena and Hermes informed which one was Medusa as she alone could be killed not the other two as they were immortal. Medusa and her two sisters were monsters with live snake heads. Athena gave Perseus a mirror as if Perseus had seen her face directly he would have turned to a stone.
