Surviving medieval art is primarily religious in focus and funded largely by the State, Roman Catholic or Orthodox church, powerful ecclesiastical individuals, or wealthy secular patrons. These art pieces often served a liturgical function, whether as chalices or even as church buildings themselves. Objects of fine art from this period were frequently made from rare and valuable materials, such as gold and lapis, the cost of which commonly exceeded the wages of the artist.
Medieval aesthetics in the realm of philosophy built upon Classical thought, continuing the practice of Plotinus by employing theological terminology in its explications. St. Bonaventure's "Retracing the Arts to Theology", a primary example of this method, discusses the skills of the artisan as gifts given by God for the purpose of disclosing God to mankind, which purpose is achieved through four lights: the light of skill in mechanical arts which discloses the world of artifacts; which light is guided by the light of sense perception which discloses the world of natural forms; which light, consequently, is guided by the light of philosophy which discloses the world of intellectual truth; finally, this light is guided by the light of divine wisdom which discloses the world of saving truth.
