I just rewatched Indiana Jones and the Last Crusade yesterday and they had some latin tablets that they showed… however, they only show it for a few seconds so I wasn’t able to get more than a few words… you’d have to freeze-frame it
In another forum on the Latin-topic I visit (it’s a German one) a fan posted the pictures of a tablet and after two threads with 5 pages the guys there had a quite nice translation…unfortunateley the pics aren’t on the server any more…
