 | | Pappus of Alexandria, who lived around the time of Roman emperor Theodosius, was the last of the great Greek geometers and one of his theorems is cited as the basis of modern projective geometry. |
 | | In some ways perhaps most amazing of all was Heron, or Hero of Alexandria, from the 1st century A.D. His writings indicate that he taught at the Mouseion since they they look like lecture notes from courses he must have given there on mathematics, physics, pneumatics, and mechanics. |
 | | Church hostility is certainly implicated, but whatever the precise motivation, the departure from Alexandria of so many scholars around this time marked the beginning of its decline as a major centre of ancient learning. |
