The importance of the calculation lies not in its accuracy, though the value differs by less that 0.4 % of the current value of roughly 3499, but that the calculation used the formalism of probability. The difficulty in such a calculation was in combining all the different data existing at the time, stretching from antiquity to contemporary observations, all with different reliabilities.
