The Byzantine humanist who triggered the Hesychast controversy was a brilliant but sharp-tongued Greek from southern Italy named Barlaam... thoroughly versed in the classics, an astronomer, a mathematician, as well as a philosopher and a theologian. Unfortunately for him, this formidable learning was coupled with an arrogant, sarcastic manner, so caustic at times that he put off even friends and allies. Born around 1290 in Calabria in southern Italy, Barlaam came to Constantinople in 1320.
