You will start in the main hall. Go upstairs, open the first door on the right side and follow the corridor. On the end is an entree to the library, so go inside.
Look at the bookcases on the left - one of the book is unnaturally embattled. Push it and then a safe-deposit will open. Take a labyrinth map.
Go upstairs, pass Artifact 1/8 (you can't take it by now) and go to the small room, full of bookcases. There are also books, which are unnaturally embattled, so push them. Another safe - deposit will open. Take pistols.
Come back near to stairs and shoot at the glass, which is protecting Artifact 1/8. Take the item. Close to the entree of small room is huge painting - jump onto.
Holding the edge you will slide down. On the wall behind the painting is button. Come back to the floor and shoot at the button - the secret passage will open.
Go downstairs and then follow the corridor. You will see boxes. Look at the cases on the left - there is an empty pail, take it.
Jump to the box and go upstairs. Push the button on the left wall and move a door - handle. This is a chamber with relics. Go upstairs - there is a small room. Shoot at the show - case and take gnomon of sundial.
