Avicenna and the Renaissance
1582
Geoffrey Chaucer wrote the Canterbury Tales in the late 14th century. Praising the knowledge and skills of a "Medical Practictioner," he states:

Wel knew he ... Avycen.

There is plenty of evidence that Avicenna's work was very important to the study of medicine throughout the Middle Ages and into the Renaissance. By mid-Renaissance many of Avicenna's writings were viewed with skepticism. Some scholars believed that Avicenna made many mistakes and faulty assumptions, while others felt that the translations were at fault. This 1582 edition was translated into Latin by Gherardo da Cremona in the 12th century. Avicenna's encyclopedic work was used as a textbook in European universities until the 17th century.
