Background on the Renaissance . . .
" During the 15th century a few English clerics and government officials had
journeyed to Italy and had seen something of the extraordinary cultural and intellectual movement flourishing in the city-states
there. That movement, generally known as the Renaissance, involved a rebirth of letters and arts stimulated by the recovery
of texts and artifacts from classical antiquity, the development of techniques such as linear perspective, and the creation
of powerful new aesthetic norms based on classical models.
