Missing folios

Yet somehow some modern authors claim that Barschius sent to Kircher not some full book but sample copies of some pages.

A copy was sent, twice, that's literally said in the 1639 letter from Barschius to Kircher. How many pages is not said.

Translation by ChatGPT3/4:
Since in my library there was a certain script written in characters that were unrecognizable, I thought it would not be inappropriate to send him an Egyptian enigma to solve. (ChatGPT4: I deemed it appropriate to send this riddle for the Egyptian Oedipus to solve.)

Therefore, imitating a script (ChatGPT4: having copied the script) from an old book (whose bearer will be its visual inspector and informant), I sent that script to your reverence a year and a half ago, so that if it pleased your reverence to devote some effort to the investigation and to make known the characters of the unknown script, that work could benefit both its Oedipus (as far as the secrets contained in the book were worthy of such an excellent work) and myself, and the common good. For it is not advisable to entrust the book itself on a long and dangerous journey; indeed, even what I sent last time did not reach Rome, as I can tell from the fact that I have not heard anything about it in all this time. Therefore, I thought it best to send it again according to custom (ChatGPT4: I thought it prudent to send another copy), which Father Moretus told me had arrived safely in the city, which made me very happy; and I will be even happier if the aforementioned book is opened with your reverence's help, so that those who can share its goodness may do so.
