The Ring and the Book continues, as the action passes to Guido’s court-appointed defense lawyer — the devoted papa of an 8-year-old namesake. The lawyer is very proud that his son is learning Latin, an essential skill for following in his footsteps. Also, it’s his son’s birthday today. So Giacinto de Arcangeli spends most of the book explaining his take on the case to his son, while explaining the Latin of his brief as well. We also hear every conceivable diminutive form of the name Giacinto. 🙂
So yeah, you don’t really have to know Latin to understand what’s going on, but there’s a lot of it interspersed in the lines. Mostly it’s funny at first, although the lawyer’s intended argument starts getting very creepy after a while.
