MONTHS AND SEASONS. 179
taking it to denote 'a conjunction,' observes as follows, "The
phases of the moon being so readily observable, it is pro-
bable that, as suggested by Professor Weber, the idea of a
period of time known as a yuga and depending upon a conjunc-
tion of certain heavenly bodies, was originally derived from
a knowledge of these phases. The Professor (Weber) further
strengthens his supposition by referring to a passage cited in
the Shaḍviṁsha Brâhmaṇa (IV, 6)* wherein the four yugas
are still designated by their more ancient names, and are con-
nected with the four lunar phases to which they evidently owe
their origin." Mr. Rangâchârya then refers to darsha, the
ancient name for the conjunction of the sun and moon, and con-
cludes, "There is also old mythological or other evidence
which leads us to conclude that our forefathers observed many
other kinds of interesting celestial conjunctions; and in all pro-
bability the earliest conception of a yuga meant the period
from new moon to new moon," that is, one lunar month. The
passage stating that it was the first dawn that set the cycle of
mânushâ yuga in motion is already quoted above; and if we
compare this statement with Ṛig. X, 138, 6, where Indra after
killing Vṛitra and producing the dawn and the sun, is said
"to have set the ordering of the months in the sky," it will
be further evident that the cycle of time which began with
the first dawn was a cycle of months. We may, therefore,
safely conclude that mânushâ yugâ represented, in early days,
a cycle of months during which the sun was above the horizon,
or rather that period of sunshine and action when the ances-
tors of the Aryan race held their sacrificial sessions or
performed other religious and social ceremonies.
There are many other passages in the Ṛig-Veda which
support the same view. But mânushâ yugâ being everywhere
