Geminus [Astro*Index]

Greek astronomer and mathematician, who flourished in the 1st century BC.

The only work of Geminus to survive is his Introduction to the Phenomena, in it, he describes the zodiac and the motion of the Sun; the constellations; the celestial sphere; days and nights; the risings and settings of the zodiacal signs; luni-solar periods and their application to calendars; phases of the Moon; eclipses; star phases; terrestrial zones and geographical places; and the foolishness of making weather predictions by the stars.

He also wrote a commentary on Posidonius' work on Meteorology.
