The Golden AgeAl-Farabi
The Second Teacher
872 – 950 CE
Al-Farabi was called "The Second Teacher" (after Aristotle) for his unrivaled mastery of logic and philosophy. His political philosophy envisioned the ideal state, and his works on music theory and classification of the sciences laid intellectual foundations that influenced centuries of thinkers.
The Golden AgeIbn al-Nafis
Discoverer of Pulmonary Circulation
1213 – 1288 CE
Ibn al-Nafis was the first physician to accurately describe pulmonary circulation, overturning Galen's centuries-old model of the heart. His discovery, made three centuries before Michael Servetus and William Harvey, is one of the most significant achievements in the history of medicine.
The Golden AgeAl-Battani
The Ptolemy of the Arabs
858 – 929 CE
Al-Battani was the most important astronomer of the medieval Islamic world, whose precise measurements refined Ptolemaic astronomy and influenced Copernicus. He accurately determined the length of the solar year, the obliquity of the ecliptic, and introduced the use of trigonometric functions into astronomy.
The Golden AgeAl-Dinawari
The Father of Arabic Botany
815 – 896 CE
Al-Dinawari was a polymath best known as the founder of Arabic botany. His "Book of Plants" was the most comprehensive botanical work of the medieval Islamic world, describing over 600 plant species with details on their growth, habitats, and uses.
