While wrapping the arena to put under the Christmas tree, we realized that the parchment that the Caesar character holds has some actual Latin on it. It's a list of Latin maxims including "Alea iacta est," "Dum spiro, spero," "In hoc signo, vinces," "Repetitio est mater studiorum," "Primus inter pares," "Fiat lux," "Quod erat demonstrandum," "De gustibus non est disputandum," and several others.
Very, very cool! Excellent attention to detail!
