adytum of god-nourished silence, as it is called in the Chaldean<br />
oracles, may be said, metaphorically speaking, to be an audacious<br />
undertaking. But the duad was called matter, as being<br />
indefinite, and the cause of bulk and division, as Simplicius<br />
observes in his comment on the Physics. And it is the cause of<br />
dissimilitude, as being in its first subsistence the infinite, from<br />
which dissimilitude is suspended, in the same manner as similitude<br />
is suspended from bound. But it is the interval between<br />
multitude and the monad, because it is yet perfect multitude,<br />
but is as it wereparturient with it, and almost unfolding it into<br />
light. Of this we see an image in the duad of arithmetic.<br />
For as Proclus beautifully observes in his Comment on the<br />
20th kc. definition of the first book of Euclid's Elements:<br />
"The duad is the medium between unity and number. For<br />
unity, by addition, produces more than by multiplication; but<br />
number, on the contrary, is more increased by multiplication<br />
than by addition; and the duad, whether multiplied into, or<br />
compounded with itself, produces an equal quantity." The<br />
duad was also called equal, because, says the anonymous author,<br />
"two and two are equal to twice two:" that is, the addition<br />
of two to itself, is equal to the multiplication of it by itself.<br />
But it is unequal, defect and abundance, as the same author<br />
observes, according to the conception of matter. For he adds,<br />
the Pythagoreans call matter homonymously with this, the indefinite<br />
duad, because so far as pertains to itself, it is deprived<br />
of morphe, form, and a certain definition, and is defined and<br />
bounded by reason and art. It is likewise alone unfigured,<br />
because, as the anonymous writer observes, "From the triangle<br />
and the triad polygonous figures proceed in energy, ad infiniturn;<br />
from the monad all figures subsist at once according<br />
to power; but from two things, whether they are right lines,<br />
or angles, a right-lined figure can never be composed."* But<br />
