Scene of an open-air pharmacy, with a border illustrating various treatments. From a hebrew edition of Avicenna, circa 1440. Abu 'Ali al-Husayn ibn 'Abd Allah ibn Sina (980-1037), commonly known as Ibn Sina or by his Latinized name Avicenna, was a Persian polymath, who wrote almost 450 treatises on a wide range of subjects, of which around 240 have survived. He is regarded as the most famous and influential polymath of the Islamic Golden Age. A severe colic, which seized him on the march of the army against Hamadan, was checked by remedies so violent that Ibn Sina could scarcely stand. On his deathbed he bestowed his goods on the poor, restored unjust gains, freed his slaves, and read through the Qur'an every three days until his death in 1037 at the age of 58.
