I am really stumped... I escaped getting crushed by using the shield in the underground space in the scriptorium. I checked out the scribe and removed everything and automatically found myself home. However, when I went through my inventory I can't do anything.
I read that I should have a some form of wheel in my notes, I don't... I tried using my compass and magnifying glass on all the items I added to my diary ... nothing happens...well, that isn't exactly true...when i click on a small engraving that looks like entrance to a tomb, it cuts away to a monk motioning me back to the underground tunnel. The walkthrough says "Use the quill on the alphabet of Philibert's stone to get TOMBE" Where is that, what am I missing? Thanks

Read Philibert's journal that you got from his body.
See the script from the tunnel that you escaped from and also the inscription from Philbert's stone.

You use the quill on that inscription - you will then highlight the word TOMBE.
You can now do the translation puzzle that uses the compass to make circle-wheel in the journal.
