Since, however, of things unequal, some are commensurate and others incommensurate, it is evident that these also must be adapted to divine natures. Hence commensuration must be referred to those Gods, through whom secondary natures are mingled with those prior to them, and participate of the whole of more excellent beings. For thus, in things commensurate, the less is willing to have a common measure with the greater, the same thing measuring the whole of each. But incommensuration must be ascribed to those divinities from whom things subordinate, through the exempt transcendency of more excellent natures, participate of them in a certain respect, but are incapable through their subjection of being conjoined with the whole of them. For the communion proceeding from first to partial and multifarious natures is incommensurate to the latter. If, indeed, _the equal_ and _the unequal_ are symbols of the mundane Gods, _the commensurate_ and _the incommensurate_ are here very properly introduced. For in things incorporeal and immaterial this opposition has no place, all things being there effable; but where there is a material subject, and a mixture of form and something formless, there an opposition of commensuration very properly subsists. Hence, as the mundane Gods are proximately connective of souls and bodies, form and matter, a division appears in them, according to _the equal_ and _the unequal_. CHAPTER XXXV. After the mundane Gods, the scientific order of discussion requires that we should consider divine souls, and the triple genera of natures more excellent than man, viz. angels, dæmons, and heroes. Previous, however, to this, that I may as much as possible unfold to the reader the whole of the Platonic theory about the Gods, I shall present him with a development of the nature of certain other divinities mentioned by Plato; and which, owing to the loss of the seventh book of Proclus, and of other theological works of the most genuine Platonists, cannot at this remote and barren period be scientifically classed.
