ic attempt to harmonise the old religious beliefs
with philosophic theories of the universe[555]. Varro, following his
teacher, held the Stoic doctrine of the _animus mundi_ the Divine
principle permeating all material things which, in combination with
them, constitutes the universe, and is Nature, Reason, God, Destiny,
or whatever name the philosopher might choose to give it. The universe
is divine, the various parts of it are, therefore, also divine, in
virtue of this informing principle. Now in the sixteenth book of his
great work Varro co-ordinated this Stoic theory with the Graeco-Roman
religion of the State as it existed in his time. The chief gods
represented the _partes mundi_ in various ways; even the difference
of sex among the deities was explained by regarding male gods as
emanating from the heaven and female ones from the earth, according
to a familiar ancient idea of the active and passive principle in
generation. The Stoic doctrine of [Greek: daimones] was also utilised
to find an explanation for semi-deities, lares, genii, etc., and thus
another character of the old Italian religious mind was to be saved
from contempt and oblivion. The old Italian tendency to see the
supernatural manifesting itself in many different ways expressed by
adjectival titles, e.g. Mars Silvanus, Jupiter Elicius, Juno Lucina,
etc., also found an explanation in Varro's doctrine; for the divine
element existing in sky, earth, sea, or other parts of the _mundus_,
and manifesting itself in many different forms of activity, might
be thus made obvious to the ordinary human intellect without the
interposition of philosophical terms.

At the head of the whole system was Jupiter, the greatest of Roman
gods, whose title of Optimus Maximus might well have suggested that no
other deity could occupy this place. Without him it would have been
practically impossible for Varro to carry out his difficult and
perilous task. Every Roman recognised in Jupiter the god who
condescended to dwell on the Capitol in a temple made with hands, and
who, beyond all other gods, watched over the destinies of the Roman
State; every Roman also knew that Jupiter was the great god of the
heaven above him, for in many expressions of his ordinary speech he
used the god's name as a synonym for the open sky.[556] The position
now accorded to the heaven-god in the new Stoic system is so curious
and interesting that we must dwell on it for a moment.
