Марк Твен

The novel is a comedy set in 6th-century England and its medieval culture through Hank Morgan's view; he is a 19th-century resident of Hartford, Connecticut, who, after a blow to the head, awakens to find himself inexplicably transported back in time to early medieval England where he meets King Arthur himself. Hank, who had an image of that time that had been colored over the years by romantic myths, takes on the task of analyzing the problems and sharing his knowledge from 1300 years in the future to try to modernize, Americanize, and improve the lives of the people.
