 George of Trebizond (Trapezuntius), who was born 

 in Crete in 1395, visited Italy between 1430 and 

 1438, and was secretary to the humanist Pope 

 Nicholas V., an ardent Aristotelian. George's work,

 his contemporary Theodore of Gaza, who was born 

 in Thessalonica about 1400, and was professor of

 With the later Latin versions we need not here

 the scientific workers who were inspired by Aristotle, 

 and of the translations into modern languages. 



The Renaissance biologists show unmistakably the Aristotle's 

 difference in quaUty which there is between Aristotle's successors. 

 physics and his biology. Hieronimo Fabrizio of 

 Acquapendente (1537-1619) knew and admired 

 Aristotle's work on embryology, and what is more, 

 himself carried out further important observations 

 on the same subject. His brilliant successor, William 

 Harvey (1578^1657), was a student of Aristotle, and
