"The Disputation of the Sacrament" by Raphael.
This fresco was painted by Raphael in the same year and in the same room that he painted the fresco "The School of Athens".
"The School of Athens" was painted in front of this fresco to symbolize that the ideas of Plato and Aristotle were leading them to the Truth that was in front of them but they couldn't see yet.
