In the city of Hamadan in Iran, right in the centre, there is a vast mausoleum dedicated to an Iranian national hero. Built in 1952, exactly 915 years after his death, it’s a great conical tower with twelve supporting columns. It’s dedicated not to a warrior or a king but to a philosopher and physician. His name is Ali Al Husayn Ibn-Sina, but he is also known as Avicenna and he is arguably the most important philosopher in the history of Islam.
Ismailimail 
This is truly a magnificent radio program on Ibn Sina(Avicenna) and
discusses his prodigious intellect especially as it pertains to his
philosophical and medical ideas, how he disagreed with his prominent father’s belief in philosophical Ismailism and came up with his own logical synthesis of God as the “Necessary Existent”. Avicenna himself in his autobiography states that his Canon of Medicine(of which the Aga Khan Museum Collection owns one of the earliest original copies) was really comic relief for him, that it was something he wrote to give his prodigious brain some down time from all the extraordinarily difficult philosophy he was inventing; it was by far his easiest intellectual task. Yet this was a 5-volume text that was used in the West until the 17th century.
