I'll post a more complete picture since the one you posted left out the ever so important top section:
Now, I've lost track of how many times I've been told that the Assumption of the Blessed Mother was "invented" by the Catholic Church in the mid-20th century. Yet, this painting was completed in the early-16th century (it was completed around 1518). The fact is that this painting was completed around the same time the Protestant Reformation BEGAN.
Titian was one of the best known painters in the world and I'm sure that some would love to say that he simply "imagined" this, but Botticini had completed this painting in 1476:
So, I guess I have two questions:
1. How can you say something was "invented" in the 1950s when there are paintings of it that were done more than 400 years before?
2. Since these paintings establish a known belief, why did none of the Reformers denounce it?
