 What makes this a Renaissance painting, as against Gentile da Fabriano's masterpiece, is the solidity, the three-dimensionality and naturalism of the figures and the realistic way in which their garments hang or drape around them.Even though it is clouds these figures stand upon, and not the earth, they do so with weight.The series of frescoes that Fra Angelico painted for the Dominican friars at San Marcos realise the advancements made by Masaccio and carry them further.
