The Six Books of Proclus on the Theology of Plato, Volume 1

Moreover, it is easy for every one to see how these things accord with what is written in the Phædrus. For the connective one accords with the back of the heaven that comprehends these. For the one and the back are the same, comprehending according to one simplicity the whole circulation. But whole is the same with the profundity of the heaven, and with as it were the bulk of it. For the celestial profundity is a whole extended from the back as far as to the arch. And end is the same with the arch. This therefore, is evident beyond every thing, and each of the other conclusions, is to be referred to the same conceptions. Hence from what has been said, it may be collected, that these three things pertain in a remarkable degree to the Synoches, viz. the one, whole, and the end [or the finite]. For what is so able to connect multitude as the one which is co-arranged with it? What is so connectedly-comprehensive of parts as whole? And how is it possible that the end [or bound,] should not be the cause of binding together things which are borne along to infinity. It terminates therefore, their progression, and brings back their dispersed section to the one essence of connection. And thus much concerning the connective triad.
