After we have stated how many of the star-cycles of
a kalpa fall in a caturyuga and in a kaliyuga, according
to Brahmagupta, we shall now derive from the number
of star-cycles of a caturyuga according to Pulisa the
number of star-cycles of a kalpa, first reckoning a
kalpa— 1000 caturyugas, and, secondly, reckoning it as
1008 caturyugas. These numbers are contained in the
following table :—

We meet in this context with a curious circumstance.
Evidently Alfazari and Yakub sometimes heard from
their Hindu master expressions to this effect, that his
calculation of the star-cycles was that of the great Sid-
dhdnta, whilst Aryabhata reckoned with one-thousandth
