AVICENNA [Abu 'Ali al-Husain ibn 'Abdallah ibn Sinai (980-1037), Arabian philosopher, was born at Afshena in the district of Bokhara.
But amid his restless study Avicenna never forgot his love of enjoyment.
The medical literature of this period is extremely voluminous, but essentially second-hand, consisting mainly of commentaries on Hippocrates, Galen, Avicenna and others, or of compilations and compendia still less original than commentaries.
On the birth of Avicenna's younger brother the family migrated to Bokhara, then one of the chief cities of the Moslem world, and famous for a culture which was older than its conquest by the Saracens.
Under him Avicenna read the Isagoge of Porphyry and the first propositions of Euclid.
