A Connecticute Yankee in King Arthur's Court

I read a book A Connecticute Yankee in King Arthur's Court.Hank Morgan works in a machine factory in Connecticut in USA. The year is 1879. He is in sixth century England by chance. He is taken a man who is a poloce to Camelot. In Camelot, King Arthur is now. Morgan meets King Arthur and lives in there together.Few years later, Morgan thinks that he wants to change things in Camelot and make people's live better. One day, he wants to go away to understand living of people. And King says that he wants to go with, too. So they change their clothes. Because it is not to find that Arthur is for 'King' by many people. Many years later, Camelot changes everything. Morgan is changed there everything.But Merlin the magician makes Morgan to sleep for thirteen centuries. He wakes up and have been a old man.I think this story looks like 'Urashima-Taro' in Japanese fairy tales.
