Other mistake: After Leonardo sets up his canvas to begin painting The Last Supper with Jesus with his disciples, he says "hold it" and then the camera flips to show the men (and Comicus) now situated behind the table. Look at the disciple in the blue tunic at the right, who first looks off to his right, then corrects his position, and faces left, with his arms extended. (00:52:32)
Other mistake: At the beginning of the Roman Empire section, there are signs that use the letter V as a substitute for the letter U. However, one of the signs says "Annual Orgy and Buffet." For some reason, the U's are not V's.
