>>> Fekri, dismissed as exaggeration and fantasy by most other Egyptologists, was determined to prove the writings were true and accurate. There. Better?

No. Too many miles between subject and verb. Unless there's a mistake, why don't you focus on content?

Oops, I missed the dangling participial phrase. Still, putting it between subject and verb doesn't fix it. It needs rewritten, but the meaning is clear enough. Maybe "Fekri's claims" instead of "Fekri."

Fekri was determined to prove the writings, dismissed as exaggeration and fantasy by most other Egyptologists, were true and accurate.

Grammar, used to correctly structure a sentence, directs attention to content, and eliminates confusion.
