Architectural beauty is a concept that is continually changing and entirely subjective. It is dependent upon who is doing the evaluating and the criteria with which they are basing their evaluation. Usually, the structure's ultimate function weighs in heavily in the determination of its beauty.Churches function as houses of God, and therefore have, up until recently, been held to higher standards of beauty than other structures. I say until recently because most of the newly erected houses of worship look like warehouses. Rather than depicting a spiritual connection with the divine through architectural beauty, their intention is to be as bare as possible on the outside in order to convey the message that it is what's inside (the fellowship of its congregation and sincerity of their devotion and faith in the concept of a plane of existence beyond our material world) that counts.

In the vault of San Vitale, the four angels standing on orbs clearly echo this symbolism with the reference to the four corners of the world” However obscure or vague the views of Plotinus regarding beauty in art seem to be upon initial consideration, through careful dissection, they can be manipulated to pertain to just about any work of art. The Basilica of San Vitale is an excellent work of architecture to use as a point of reference [...]
[...] The mosaic that best represents Plotinus's diametrically opposed concepts of beauty and ugliness is the one that is located on the left side of the apse in the church, “Justinian, Bishop, and Attendants.” Through the eyes of Plotinus, this mosaic is beautiful because its flat, stylized figures appear to be gazing off into space, as if in a trance. Symbolic of metaphysical attitude, the figures seem to be lost in the contemplation of divine nature.
