Milman, History of Latin Christianity , VIII 259, says of him:⁠—

“Albert the Great at once awed by his immense erudition and appalled his age. His name, the Universal Doctor, was the homage to his all-embracing knowledge. He quotes, as equally familiar, Latin, Greek, Arabic, Jewish philosophers. He was the first Schoolman who lectured on Aristotle himself, on Aristotle from Graeco-Latin or Arabo-Latin copies. The whole range of the Stagirite’s physical and metaphysical philosophy was within the scope of Albert’s teaching. In later days he was called the Ape of Aristotle; he had dared to introduce Aristotle into the Sanctuary itself. One of his Treatises is a refutatation of the Arabian Averrhoes.
