How and why did renaissance humanists, artists, and musicians revive classical traditions?

This is my answer and explantions  - Humanism, an educational and philosophical outlook that emphasizes the personal worth of the individual and the central importance of human values as opposed to religious belief, developed in Europe during the Renaissance, influenced by the study of ancient Greek and Latin literature and philosophy. Humanism thus began as an educational program called the humanities, which inculcated those ancient secular values which were consistent with Christian teachings. The Renaissance humanists were often devout Christians, but they promoted secular values and a love of pagan antiquity.
