According to Hardouin, the majority of classical Greek and Roman literature had not been produced by Greek and Roman authors. Instead, it had been forged during the Middle Ages by a group of Benedictine monks.
Close but no cigar Hardouin.
If it wasn't FOR the monks(1) it would have been lost, but they didn't 'forge' it.
I can't recall if was the Benedictines, but Monks in 'England' were involved in copying the 'Classics'. (The History Channel is never wrong)
Related is the “Piso Theory” — the claim that the New Testament (or perhaps it was the entire Bible) was hoaxed by the Roman-era Piso family (related to Julius Caesar); the joker who used to peddle that one had a common refrain when challenged — “I’m not here to debate, I’m here to inform.” :’D
