MONTHS AND SEASONS. 167
the Navagvas are said to have completed their sacrifices in
ten months. Sâyaṇa's explanation is, therefore, fully war-
ranted by these texts, and very probably it is based on
some traditional information about the Dashagvas. Prof. Lig-
nana of Rome,* suggests that the numerals navan and dashan
in these names should be taken as referring to the period of
gestation, as the words nava-mâhya and dasha-mâhya occur in
the Vendidad, V, 45, (136), in the same sense. Thus interpreted
Navagva would mean 'born of nine months,' and Dashagva
'born of ten months.' But this explanation is highly improb-
able, inasmuch as we cannot first suppose that a number of
persons were born prematurely in early times, and secondly
that it was specially such persons that attained almost divine
honours. The usual period of gestation is 280 days or ten
lunar months (V, 78, 9), and those that were born a month
earlier cannot be ordinarily expected to live long or to perform
feats which would secure them divine honours. The reference
to the Vendidad proves nothing, for there the case of a still-
born child after a gestation of 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10
months is under consideration, and Ahura Mazda enjoins that
the house where such a still-born child is brought forth
should be cleaned and sanctified in a special way. Prof.
Lignana's explanation again conflicts with the Vedic texts
which say that the Dashagvas were ten in number (III, 39,
5), or that the Navagvas sacrificed only for ten months
(V, 47, 5). Sâyaṇa's explanation is, therefore, the only one
entitled to our acceptance. I may here mention that the Ṛig-
Veda (V, 47, 7 and 11) speaks of ten months' sacrifice only in
connection with the Navagvas, and does not mention any sac-
rifice of nine months. But the etymology of the names now helps
us in assigning the ten months' sacrifice to the Dashagvas and
