From wiki: In aesthetics, the sublime (from the Latin sublīmis) is the quality of greatness or vast magnitude, whether physical, moral, intellectual, metaphysical, aesthetic, spiritual or artistic. The term especially refers to a greatness with which nothing else can be compared and which is beyond all possibility of calculation, measurement or imitation.
