Avicenna, known as Abu-Ali Ibn Sina, was one of the most influential thinkers of the medieval Islamic world. Avicenna was born during the Golden Age of Islam – 980 AD, who was a self-taught intellectual.

He grew up near Bukhara, in the village of Afshana, in present-day Uzbekistan. Avicenna learned Indian arithmetic from a grocer. At a young age, he studied Aristotle's metaphysics intensively, and from the age of 16 he began to study medicine.

Within the framework of the Islamic religion, he was able to critically assimilate ancient philosophy and science and systematize all the knowledge of his time. His main work is a philosophical encyclopedia covering logic, physics, mathematics and metaphysics.

Ibn Sina's poetic legacy has reached us partially (he wrote in Arabic and Persian). He expressed his philosophical views in his poems. In this regard, the "Poem on the soul" is worth noting. He preached the goodness of science and education. Ibn Sina's philosophical-artistic works "Salaman and Absal", "Letter to the Bird" and "Alive, Son of the Vigilant" are allegorical in nature, which in terms of plot is close to Dante's "The Divine Comedy". Ibn Sina is also interesting as a translator and literary theorist. He has commentaries on Aristotle's "Poetics" and Arab poet Ibn Al-Rumi Diwan. Ibn Sina (popular name - Bu Ali) became the hero of the fairy tales of almost all the peoples of the Middle East.

Ibn Sina's most important medical treatise "The Canon of Medicine" was translated into Latin in the 12th century and first published in Milan in 1473, and the original Arabic version was printed in Rome in 1593. There are 30 editions of this work. In it, the author deals with the cultivation and physiology of plants, especially medicinal plants.

He hypothesized that infectious diseases are caused by invisible organisms and spread through air and water. He rejected the idea that mental illnesses were caused by evil spirits. Ibn Sina accurately described many diseases. He attached a lot of importance to hygiene and diet. He created a new pharmacy. His pharmacopoeia includes many remedies of folk medicine, especially Chinese medicine.

In 1037, Avicenna suffered from a severe intestinal disease and died at the age of 58. He was buried in Hamadan, Iran.
