"What makes the Renaissance different? Renaissance paintings look more realistic, good. What else? There are more decapitations, absolutely. You feel slightly attracted to the naked men and women, OK. Fewer weird-looking Jesus babies. Good, good. And what about this? Slide. Remember this cave painting? Renaissance painters were far less concerned with skinny, stick-figure bird men who hold staffs and are either standing or laying down in the vicinity of bison; instead, they were more interested in religion, history, boobies, wee-wees, ca-ca’s, the Renaissance, and random people standing in the background."
