Why do you think Rick Riordan included this myth in The Lightning Thief?

Becuase it was to show modern day Perseus and to show what’s right

Explanation:

Rick Riordan included the myth of Perseus to show us that Percy is the modern-day Prometheus fighting for what is right. In the myth of Prometheus, the hero is a less powerful god called Prometheus, and in The Lightning Thief, the hero is a boy with special powers called Percy Jackson.
