Where to start?

Oh, goodness.  This has been an interesting day so far!

I bought a book this morning; it was labeled 5 Euros, and in tatters.  "Tre Meridiani", by one Msgr (?) di Scadre.  Printed by a Lyonnese printer.

Oh, and did I mention it's from 1599?  And signed?  And... that it's full of sheet music?

So I didn't sweat the 5 Euros.  It's mine now.

More pictures forthcoming.
