“Within the time span of a single generation surrounding the year 1500, Leonardo, Michelangelo, and Raphael created their many masterworks of the High Renaissance, revealing the birth of the new human as much in da Vinci's multiform genius and the godlike incarnations of the David and the Sistine Creation of Adam as in the new perspectival objectivity and poietic empowerment of the Renaissance artist; Columbus sailed west and reached America, Vasco da Gama sailed east and reached India, and the Magellan expedition circumnavigated the globe, opening the world forever to itself; Luther posted his theses on the door of the Wittenberg castle church and began the enormous convulsion of Europe and the Western psyche called the Reformation; and Copernicus conceived the heliocentric theory and began the even more momentous Scientific Revolution. From this instant, the human self, the known world, the cosmos, heaven and earth were all radically and irrevocably transformed. All this happened within a period of time briefer than that which has passed since Woodstock and the Moon landing. (p. 4)”
