Word Request: a word that means "taken over a long span of time"

Question

I'm hoping that this request makes sense -

For the past 14 years of my life I've half-written a story that goes on in my head. I've always struggled for a name to call it, but have recently taken to referring to it as "The Anthology," mostly because in my head "anthology" relates to a story that takes place over a large period of time. I decided to look up anthology, and it doesn't exactly mean what it connotes to me. I've tried a few google searches and a search on here, but no luck -- is there such a word?

To give a hint at the span of time I'm referring to, the story starts about 14,000 years ago and ends far off into the future.

Thanks for any help!

P.S. If there is a word in another language that is close, I would love to hear it (and which language it comes from)

Answer 1

Saga is sometimes used for long-span, involved narratives. It might connote old northern epics but I've remembered it now in connection with The Forsyte Saga (which tells a story of a large family through several generations in late 19th/early 20th century, London).

Also, looking up this word might bring in more suggestions.
