Frederick II was unusually modern in his sensibilities. Sicily was a cultural melting pot in the thirteenth century and Frederick ended up speaking several languages. He protected Jews and Muslims in his realms and prosecuted Christian heretics throughout his thirty-year reign. He was a polymath with interests ranging from sculpture, architecture, and poetry to mathematics and science in many forms, earning him admiration from his contemporaries who called him Stupor mundi, "Wonder of the World." His lifelong interest in hunting with birds of prey led to the writing of the classic work De Arte Venandi cum Avibus (The Art of Falconry), which is still in print. Based on the latest scholarship and written for the general reader, Frederick II: The Wonder of the World by Richard Bressler provides the complete story of this complex and fascinating man.
