_Alexandria_, famous for Learning and Merchandize, but particularly for a School or Academy, of which _Theon_, the Father of _Hypatia_, was Master.
After _Alexander the Great_ had founded _Alexandria_ in _Egypt_, as the Center of Commerce in the Empire he was projecting, this City soon became a flourishing Mart for Learning as well as for Merchandize. The Fame of the _Alexandrian School_, and of the _Alexandrian Library_, reached much further than the Name of _Alexander_ himself; or at least they carried it, whither it could never have reached without their Means. This was the most proper Tribute, that could in Gratitude be paid to the Memory of a Prince so ambitious of Glory: As indeed no private Persons, no more than Potentates, will ever do any thing praise-worthy without the Prospect of a long-lived Reputation, the most effectual Spur to laudable and arduous Undertakings. The Succession of the great Men that presided in this School, may be learnt out of the Works of those, who have purposely written on such Subjects. My Design however obliges me here to mention one of them, namely _Theon_, who governed that Academy with much Applause in the latter part of the fourth Century.
