In 1345 he personally discovered a collection of Cicero’s letters not previously known to have existed, the collection Epistulae ad Atticum, in the Chapter Library (Biblioteca Capitolare) of Verona Cathedral
So basically a guy goes into a library, rummages for a while, and finds ~1400 years old text no one knew was there
Do we still have places that store texts (like libraries, but doesn’t have to strictly be a library) where we don’t have everything catalogued and we don’t know what might be inside?
Interesting indeed
But also those two are cases when we discovered more or less “working copies” of interest.
Has there been a similar find of a text that was copied and given (I’m trying to broadly cover a meaning of “published” here)
