The word "renaissance" means . the period was characterized by a renewal of interest in classical ideas from ancient . in addition, it represented a shift from a focus on to more ideas.

  Yet the Renaissance was more than a "rebirth." It was also an age of new discoveries, both geographical (exploration of the New World) and intellectual. Both kinds of discovery resulted in changes of tremendous import for Western civilization. In science, for example, Copernicus (1473-1543) attempted to prove that the sun rather than the earth was at the center of the planetary system, thus radically altering the cosmic world view that had dominated antiquity and the Middle Ages. In religion, Martin Luther (1483-1546) challenged and ultimately caused the division of one of the major institutions that had united Europe throughout the Middle Ages--the Church. In fact, Renaissance thinkers often thought of themselves as ushering in the modern age, as distinct from the ancient and medieval eras.
