In the Sasau Monastery in Kingdom Come: Deliverance, you can get the «Scattered Pages» quest to find ten pages. They are quite well hidden, so let's take a detailed look at where to find them.
To get the quest in the Sasau Monastery, you need to talk to Brother Librarian during the main quest «Needle in a Haystack.» Ask about the forbidden books, one of which is needed by Scribe Nevlas. In return, he will ask you to find 10 pages of a lost book.
Searching for the pages of Ovid's «The Art of Love» around the monastery is best done at night, as you'll need to pick locks on doors and chests in public areas. A monastery key will be very useful: the easiest way to get it is to take it from the cupboard in the far room behind the kitchen.
As a reward, you get a key to the cupboard with forbidden books. By the way, you can also open the cupboard with a lockpick if you are skilled in lockpicking.
