Speaking of Albertus Magnus, let's have a short visit to him. Albert (also: Albertus Teutonicus; Albertus Coloniensis; Albert the Great, Albert the German, Albert von Lauingen), polyhistor, philosopher, jurist, natural scientist, theologist; Dominican und bishop of Regensburg. Being a bright light in the Middle Ages, he later was recognized as Doctor of the church and got the honorary title 'doctor universalis'. His 70 treatises and books would fill ca. 22,000 printed pages, a treasure that is still evaluated incompletely.
An important consequence of his works is the foundation of Christian Aristotelianism, thus of scholasticism and eventually of modern natural science. His compilation 'De animalibus' listed 113 quadrupeds; 114 flying, 140 swimming und 61 creeping animals as well as 49 worms. Referring to Aristotle, he explained that also the lower animals deserve attention, because of the need for researching their variety of forms in order to praise their creator and his act of creation. (No, we are not talking about 'Intelligent Design' or creationism here. I don't think that Albert's spirited wit would have supported this caricature of medieval thinking.)
