374 THE ARCTIC HOME IN THE VEDAS.
stated above must, therefore, be taken to represent the Arctic
climatic conditions prevailing in the ancient home in the far
north ; and the correctness of the explanation is proved by
the discussion in the foregoing chapters. With regard to the
custom of kindling a fire on the ninth day of Din or the tenth
month, noticed in the Bundahish, it seems to me that instead
of taking it to be an indication that winter “has come,” it is
better to trace its origin to the commencement of winter at
that time in some part of the original home ; for if a fire is to
be kindled there is greater propriety in kindling it to com-
memorate the commencement of winter rather than the expiry
of two out of five winter months. If the custom is so inter-
preted, it will imply that a year of nine months and ten days
was once prevalent in some part of the Aryan home, a conclu-
sion well in keeping with the ancient Roman year of ten
months. But apart from this suggestion, there is a striking
coincidence between the Vedic and the Avestic tradition in this
respect. According to the Bundahish (XXV, 20), the year is
divided into four seasons of three months each, Farvardîn,
Arḑavahisht and Horvadaḍ constituting the season of the
spring ; Tîr, Amerôdaḍ and Shatvaîrô the summer ; Mitrô,
Âvân and Âtarô the autumn ; and Dîn, Vohûman and Spen-
darmaḍ, the winter. The fortieth day of Sharad or autumn
would, therefore, represent the tenth day (Abân) of Avân ;
and the Vedic statement discussed in the ninth chapter, that
Indra's fight with Shambara commenced “ on the fortieth
day of Sharad ” agrees well (only with a difference of ten
days) with the statement in the Bundahish that the winter in
the Airyana Vaêjo commenced with the month of Âvân the
second month in autumn. We have thus a very close resem-
blance between the Vedic and the Avestic tradition about the
end of summer in the original Arctic home ; and the corres-
ponding Roman and Greek traditions have been previously
noticed. In. short, a year of seven or ten months sun-shine
