Hipparchus the Astronomer is honored on a few rare issues from Nicaea, where he was born circa 190 BC. His importance to classical astronomy is unsurpassed, as he compiled the first star chart, calculated the sizes of the sun and the moon, determined the length of the seasons, and utilized a trigonometry table before any other mathematician.
