Respuesta :
Perhaps the part with Medusa, when he uses a mirror so as not to look at her directly and be turned to stone?
Answer:
Athena gives Perseus a mirror so he does not look directly at Medusa.
Explanation:
Medusa could turn into stone anyone who looked directly to her. Key word being "directly". With the use of a mirror, Perseus could look around by looking at the mirror and, by doing it, he was free from the chance of accidentally staring at Medusa.
