BITHYNIA, Nicaea. Julia Mamaea. Augusta, AD 222-235. Æ Diassarion (23mm, 7.02 g, 6h). ΙΟΥΛΙΑ ΜΑΜΑΙΑ ΑΥΓ, draped bust right / ΝΙΚΑΙΕΩΝ ΙΠΠΑΡΧΟN, Hipparchus the astronomer seated left on basis, wearing himation over lower limbs; to left, globe on small column. Unpublished. Dark brown patina with slight earthen deposits. Near VF. Extremely rare, unpublished.

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 moon, determined the length of the seasons, and utilized a trigonometry table before any other mathematician. His coins are known for the Antonines, Severus Alexander, and the family of Valerian and Gallienus. This is the first appearance on a coin of Julia Mamaea and the first on any empress.
