I think Jason fits very well in the "cycle of the hero" because...
Birth/home: His father was the wise king, Iolcus but his throne was taken over from Jason's uncle, Pelias and Iolcus was prisoned so Jason was about to be murdered right after the birth but Jason's mother hid him in the cave of Chiron.
Elixir: Jason's elixir was the golden fleece. Jason has to get it to get back his throne.
Helpers: The Helpers of Jason are the Argonauts. The Argonauts are the group of talented people who helps Jason to get the golden fleece.
Call to adventure: when Jason grew older, he goes to Pelias to get his throne. Pelias told Jason that if he brings golden fleece then Pelias is going to give him back the throne.
Helpers/amulet: The helpers and amulet of jaon are Chiron and Chiron's sword. They gave him strenght and hope to accomplish his quest.
Tests: Jason and his argonuats had many dangerous test during the journey. For examples, they had to go through the clashing rocks, fighting with fire breathing bulls and the guard of golden fleece,dragon. All the tests that Jason and Argonauts have gone through made them stronger and gave them courage.
Climax/Final battle: Jason had final battle with Medea when she was sending jason's Argonauts in to the underworld. With Chiron's sword which Jason believed, he defeated medea. The Argonauts got out of underworldd and accomplished their quest.
Return/Flight: After the dangerous quest, Jason and his Agonauts go back to Palies and get back his proper throne.
There are very many different stories of Jason and the Argonauts myth. All the stories have differences. In the video, Medea was on evil side which tries to kill jason and he Argonauts but in some myth, Medea becomes a very important woman to jason who helps him to go through all kinds of dangerous tests. In some of the stories, Jason is very weak but Jason in the video was very strong and courageous hero. I think these myth changed in many different ways when in moved mouth to mouth. however, they all contins same ideas that Jason goes on a journey with Argonaut to find back his throne.
Some people believe that [Jason and the Argonauts] is real. However, I don't think the myth Jason and Argonauts is real because there is no such creatures as fire breathing bull and dragon so It is very hard to say that it is real but it's not hundread percent wrong because it has many evidence to back it up.
