Frederick II

Died 13 Dec 1250 at age 55 (born 26 Dec 1194).Frederick II of Hohenstaufen was a German emperor and ornithologist who was a German ruler, residing in Sicily. He was a multilingual man of learning, who corresponded with and patronized scholars. He battled with the papacy, but otherwise practiced religious tolerance, and interacted with learned Jews, Muslims and Christians. His interest spanned science, especially natural history. He kept a menagerie which at various times had not only monkeys and camels, but also a giraffe and an elephant. His notable contribution to scientific ornithology was with a six-volume work, De arte venandi cum avibus (c.1244-48). In addition to some treatment of falconry, he presented his own observations (rather than perpetuating accepted hearsay knowledge) with remarks on hundreds of kinds of birds, with generalizations on their behaviour, anatomy and physiology. «[Miniature painting of Holy Roman Emperor Frederick II with a falcon from De arte venandi cum avibus, in Vatican Library.]
