Quadrivium

The quadrivium (rarely: quadrivia) comprised the four subjects, or arts, taught in the Renaissance Period, after teaching the trivium. The word is Latin, meaning "the four ways" (or a "place where four roads meet"), and its use for the 4 subjects has been attributed to Boethius or Cassiodorus in the 6th century. Together, the trivium and the quadrivium comprised the seven liberal arts (based on thinking skills), as opposed to the practical arts (such as medicine and architecture).
