The Sand Reckoner was a mathematical treatise by Archimedes in which he tried to calculate the number of grains of sand that would fill the universe. His estimate used the heliocentric model of Aristarchus, but could not measure stellar parallax. It had many underestimations that yielded a universal diameter of only about 2 light-years, but coincidentally matched one value for the known observable universe (10^63 grains having 10^80 nucleons).
