Old book identification

by Oldbookman

Please help me identify this book that I have come across. It is very old, and looks like it's maybe in Latin? Anyone know what type of literature it is?

Also I have come across this old looking pendant. Does anybody have any idea how it was displayed or who the man is on it?
