The Donatello and Settignano sculpture The Martelli Saint John the Baptist, ca. 1440-1457 from the Museo Nazionale del Bargello still holds my heart. You feel the revival of Neoplatonic philosophy during the Italian Renaissance, apparently through the publication of this kind of theory, was of influence here, maybe their nighttime ascension philosophy. Cosmology definitely feels like it had an influence, patterns of the stars and the heavens transcribed through the heart via God. The blanket coverage of a sky dominated by stars must be Gods divine instruction plan to communicate a feeling within the heart to take us to Heaven via the angel's wing. Perspective was worked out divinely between this pair to give us double heart strength. You feel this more about the perspective of Saint John's head rather than his torso and this would be a whole process of philosophy of all the thinking that equals one given moment in time. There has certainly been some beautiful philosophers thinking and equating God. God gave them wings.
