Of Euclid, as the founder (according to Proclus) of the Alexandrian Mathematical school, I must of course speak first. Those who wish to attain to a juster conception of the man and his work than they can do from any other source, will do well to read Professor De Morgan's admirable article on him in "Smith's Classical Dictionary;" which includes, also, a valuable little sketch of the rise of Geometric science, from Pythagoras and Plato, of whose school Euclid was, to the great master himself.英文原著 · 《Alexandria and her Schools》
