SF short story about history & myths

[bonniel]

I've been searching for a story I read in an anthology quite a few years ago. In the future someone invents a machine to bring people from past to the present. When people get bored with that, he brings back the myths. Some were outright myths - gods & goddesses. Others were historical myths, such as JFK as a bloodied martyr, which confused the real JFK.

I don't remember title or author.

Thanks in advance!

SF book or poss short story about a guy becoming god or god like

[ashesashes09]

I think it was a short story or novella by Stephen King but I haven't been able to find it so I may be wrong. I read it at least 5 years ago so its not something newly published. In it the main character becomes increasingly ill over the course of the story. Throughout the story he and two other characters who are either his friends or colleagues try to find out whats happening to him. At the end of the story they are in a car, the main character is in the backseat and in an immense amount of pain and his head growing and becoming grotesquely large. As the story closes his eyes and mouth start expanding and becoming black holes. I think he realizes he's becoming a god or something godlike at this point. I distinctly remember him either saying or thinking 'I fear I will not be a loving God', or something similar as the story ends.

Does this sound familiar to anyone? Its drying me crazy that I cannot find it.
