Sinan Bin Sabah

A Persian physician memorized the entire Quran by age 10 and was practicing medicine by age 16. By 18 he had cured a sultan that no other doctor could help. The textbook he wrote in his 30s became the operating manual for every European doctor for the next 600 years. I started reading about him at midnight and could not believe one teenager had personally built so much of the foundation of modern medicine. His name was Ibn Sina. The book is called The Canon of Medicine. Every modern clinical trial. Every evidence-based drug protocol. Every pharmacology textbook. Every medical school curriculum that teaches doctors to observe before they prescribe. All of it traces back to a Persian teenager who finished his medical education before most modern students finish high school. Ibn Sina was born in 980 CE near Bukhara, in modern-day Uzbekistan. His father was an Islamic scholar who employed the best tutors money could buy. The tutors started failing to keep up with him almost immediately. By age 10 he had memorized the entire Quran word for word. By 12 he was correcting his tutors on points of law. By 14 he had outpaced his teacher in mathematics and started learning on his own. By 16 he was treating patients in his neighborhood. He later wrote, with no false modesty, that medicine was an easy subject and he had mastered it quickly. He hit a wall around 17. He could not understand Aristotle's Metaphysics. He read the book forty times and still could not grasp it. Then he picked up a commentary on it by Al-Farabi in a Bukhara bookshop for a few coins, read it overnight, and suddenly the entire system of Greek philosophy snapped into place. He went home and gave alms (money or goods) to the poor in gratitude that he had finally understood. A year later the news of his medical skill reached the sultan of Bukhara, Nuh ibn Mansur, who was suffering from an illness no doctor in his court could cure. Ibn Sina was called in. He treated the sultan. The sultan recovered. The 18-year-old asked for one thing in payment. Access to the royal library. The library of the Samanid sultans in Bukhara was one of the greatest in the Islamic world at that time. Ibn Sina spent the next year inside it reading everything he could find. He later wrote that by age 21 he had absorbed everything written by every major scholar before him, and that the rest of his career was just refining what he had already understood as a teenager. He spent the next decade as a wandering physician and political advisor. Empires were collapsing across Persia and Central Asia. He moved from court to court, treating princes, drafting legal documents, escaping invasions, hiding from enemies who wanted to kill him for his association with rival rulers. He wrote at night while moving between cities by day. He was imprisoned at least once. He kept writing. In his 30s and 40s he produced The Canon of Medicine. A five volumes book at least a million words. A complete synthesis of every medical tradition he could find. Greek medicine from Galen and Hippocrates. Persian medicine from his own tradition. Indian medicine from Ayurvedic texts. His own clinical observations from thousands of patients. The Canon was translated into Latin in the 12th century. It was reprinted more than 30 times in the 15th and 16th centuries alone. It was the standard reference text at the University of Paris, the University of Bologna, and Oxford well into the 17th century. William Osler, one of the founding fathers of modern medicine, called it the most famous medical textbook ever written and said it served as a medical bible for a longer period than any other book in human history. The part that most people miss is what was actually inside it. He laid out clear rules for testing whether a drug works rules that still look like modern clinical trials. The drug must be pure, tested on a single condition, and checked against opposite conditions for consistent results. Effects must be seen repeatedly, with timing that matches the treatment. And it has to be tested on humans, since animal results don’t always carry over. A thousand years before the modern clinical trial existed, he had written its protocol. He defined medicine itself in a sentence that has never been improved on. Medicine is the science by which we learn the various states of the body in health and when not in health, the means by which health is likely to be lost, and when lost, is likely to be restored. He insisted that prevention came before treatment. He argued that lifestyle, diet, exercise, and sleep mattered as much as drugs. He was right by a thousand years. He documented hundreds of conditions with such precision that European doctors were still using his diagnostic categories in the 1700s. He died in 1037 at age 57. He was on a military campaign with one of the rulers he served when he developed colic. He treated himself with what he believed was the correct remedy. The remedy did not work. He died near the city of Hamadan in modern Iran. His tomb is still there. His own assessment of his life is one of the most honest things any genius has ever written about themselves. He said he had lived a wide life rather than a long one and that he preferred it that way. The Canon is digitized at the Library of Congress. The original Arabic version is preserved at multiple universities. Free English translations exist online. The medical textbook that trained every European doctor for half a millennium is sitting one click away from you. Most modern doctors have never heard the author's full name.
