With respect to the appellation truth, perhaps it was so
called because truth is the harmonious conjunction of that
which knows with that which is known; and the hexad, as
we have before shown, is most eminently harmonic.
Again, according to the anonymous author it was called fardarting
Trivia, and pertaining to two times; the
first of these because the triad which is Hecate being hurled
jorth (Bohagav) and as it were composed (i.e. joined with
another triad) generates the hexad. "But it was called Trivia,"
says he, "perhaps from the nature of the goddess. And it is
probable that it was thus denominated, because this number is
first ailotted the motions which take place in the three intervals
(length, breadth and depth,) each of which receives a twofold
division from circumstances; (viz. motion according to length,
is either backwards or forwards, according to breadth, is either
on the right hand or the left, and according to depth, is either
upwards or downwards.) But it was denominated pertaining
to two times, from the distribution of the whole of time being
effected by six signs of the zodiac above, and six under the
earth. Or it was thus called, because time is allied to the triad,
since it consists of three parts, and the hexad is formed from
two triads."
With respect to the epithets Persea and triformed, the hexad
appears to have been thus denominated for the same reason
that it was called Trivia; for it is well known that Diana is triformed,
and this goddess is called Persia by Orpheus in the introduction
to his hymns. But we are informed by the anonymous
writer that the hexad was called Amphitrite, because it
has a triad on each side of it; and Anchidice, because it is especially
proximate to the pentad, which as we have before
shown was called by the Pythagoreans 8~ dice, or Justice.
Lastly, the same author informs us, that it was called Thalia
and Panacea, the former on account of the harmony of its com-
