I'm looking for a game i played back in the late 90s.

I played it on a PC, it was either in MS-DOS, Window 95 or 98.

It was a first person escape game similar to MYST, but it had more Da Vinci flavor. I remember the setting was a castle or a dungeon in a castle. The goal is to escape by finding clues. One of the puzzle was the Cryptex like the image. There were also other Da Vinci sketches like his flying machine, etc...

Please help me, thank you.
