Geminus

? · Rhodes

Geminus was a Greek astronomer and mathematician active in the 1st century BCE, likely working in or around Rhodes within the Stoic intellectual tradition. He is best known for his "Introduction to the Phenomena" (Eisagoge eis ta phainomena), a clear and influential elementary handbook of astronomy that surveys the zodiac, the constellations, the celestial sphere, lunar months, calendar cycles, and the geography of climatic zones. The work is valued today both as a teaching text and as a witness to earlier Greek astronomical thought, including ideas associated with Hipparchus and Posidonius.

About Rhodes

Rhodes is the largest of the Dodecanese islands of Greece, in the southeastern Aegean off the coast of Asia Minor. In the Hellenistic and Roman periods it was a renowned centre of rhetoric, philosophy and astronomy: the Stoic Panaetius was a native, the Stoic Posidonius ran his school there, and the astronomers Hipparchus and Geminus worked on the island. Herod the Great met Octavian at Rhodes around 30 BCE and was confirmed as king of Judea. The island was later held by the Knights Hospitaller, the Ottomans and Italy before joining Greece in 1947. Its ancient Jewish community built the Kahal Shalom synagogue in 1577, the oldest in Greece; most of the community was deported and killed under German occupation.
