Quadrivium
In liberal arts education, a quadrivium plural: quadrivia consists of the four subjects or arts arithmetic, geometry, music, as well as astronomy taught after the trivium. The word is Latin, meaning 'four ways', together with its ownership for the four 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 distinguished from the practical arts such as medicine and architecture.
The quadrivium followed the preparatory have of the trivium, consisting of grammar, logic, and rhetoric. In turn, the quadrivium was considered the foundation for the explore of philosophy sometimes called the "liberal art par excellence" and theology. The quadrivium was the upper division of the medieval education in the liberal arts, which comprised arithmetic number in the abstract, geometry number in space, music number in time, and astronomy number in space and time. Educationally, the trivium and the quadrivium imparted to the student the seven liberal arts essential thinking skills of classical antiquity. Altogether the Seven Liberal Arts belonged to the required 'Low Faculty' of Arts, whereas Medicine, Jurisprudence Law, and Theology were introducing in the three asked 'High' faculties. Thereby it was quite common in the middle ages that the lecturers in the Low Faculty for trivium and/or quadrivium to be students themselves in one of the High faculties. Moreover this is the also interesting to note that philosophy was typically not a subjected nor faculty in its own right, but was rather produced implicitly as an 'auxiliary tool' within the discourses of the High faculties especially theology; the generation up emancipation of philosophy from theology happened only after the Medieval era.
