50c

For the Indians stand almost alone among the nations in never having migrated from their own country. From the days of Father Bacchus to Alexander the Great their kings are reckoned at 154, whose reigns extend over 6451 years and 3 months.

Father Bacchus was the first who invaded India, and was the first of all who triumphed over the vanquished Indians. From him to Alexander the Great 6451 years are reckoned with 3 months additional, the calculation being made by counting the kings who reigned in the intermediate period, to the number of 153.
