nights within the Arctic Circle. Whether Ahanî means a
couple of Day and Night distinct from Uṣhásá-naktá in every
place where the word occurs, it is difficult to say. But that in
some places, at least, it denotes a peculiar couple of the Day and
Night, not included in, and different from, Uṣhásá-naktá is evident
from IV, 55, 3. Now if Ahanî really means the couple of the
long day and the long night, as distinguished from the ordinary
days and nights, there is another way in which these two couples
can be differentiated from each other. The ordinary days and
nights follow each other closely, the day is succeeded by the night
and the night by the day; and the two members of the couple,
representing these days and nights, cannot be described as
separated from each other. But the long night and the long
day, though of equal duration, do not follow each other in close
succession. The long night occurs about the time when the sun
is at the winter solstice, and the long day when he is at the sum-
mer solstice; and these two solstitial points are separated by
180°, being opposite to each other in the ecliptic. This
character of Ahanî seems to have been traditionally known in
the time of the Âraṇyakas. Thus the Taittirîya Âraṇyaka,
I, 2, 3, in discussing the personified Year,* first says that
the Year has one head, and two different mouths, and then
remarks that all this is 'season-characteristic,' which the
commentator explains by stating that the Year-God is said to
have two mouths 'because it has two Ayanas, the northern and
the southern, which include the seasons. But the statement
important for our purpose is the one which follows next. The
Âraṇyaka continues "To the right and the left side of the Year-
God (are) the bright and the dark (days); and the following verse refers
to it:—'Thy one (form) is bright, thy another sacrificial (dark), two
