I've spoken with Niklas and we're pretty convinced SANCTA must have had Marble to be able to build Oracle in 2 turns! Cav were number 1 on mfg and we were second, so we also reckon they used 3 chops to do this.
This means SANCTA have teched Mysticism, Med/Poly (if poly then MS beat them by 1 turn!) Priesthood and Masonry.
They definitely don't have Writing which is why they didn't get CoL. They've probably taken Metal Casting, or more likely Monarchy. If their GNP plummets next turn it will be due to a revolution, so we'll know they got Monarchy.
They've won Oracle, which is a pain, but they didn't get a very expensive/useful tech out of it a least
