Masaccio, talk about how he was the first to use linear perspective. "The Holy Trinity" is the most important painting of all time, fuck the mona lisa, its just a painting of a beautiful women, sure its an amazing painting, but "the Holy Trinity" takes the fucking cake. Imagine seeing that shit for the first time, it was like looking into another world, and that world was directing you, the viewer. People traveled the world to see this shit. You could easily talk about that.
