Donatello is the heart. Other geometers of the heart took a comprehension of perspective to the centre of the earth. This they thought was the microcosm of the macrocosm of the universe. Therefore, the Sun was the centre and the planets existed around this. The comprehension was used in sculpture to suggest the centre of the chest was the Sun and the planets were suspended around this, the Italian Renaissance sculptors had to accommodate for the planets in the breast cavity and it would appear divinely formed. God was giving them a divine message but this one would feel was about the centre of the heart equalling the divine element not the Sun and the divine geometry of the heart. This is the basis of Neoplatonism and the theory of philosophy from Plato's day. This was a theory about love. God gave it wings with sculpture in the round. They took the knowledge to Heaven with them, a heartfelt knowledge only known to the heart, we are here to evaluate Gods love in our hearts and thank you dear God for Donatello.
