The illustrious founder intended it not only for the capital of Egypt, but of his immense conquests, and the commercial advantages which its situation commanded continued to improve from the time of Alexander till the invasion of the Saracens in the seventh century. The commodities of India were brought there, and thence dispersed to the different countries around the Mediterranean. Alexandria is famous, among other curiosities, for the large library which the pride or learning of the Ptolemies had collected there, at a vast expense, from all parts of the earth. This valuable repository was burnt by the orders of the caliph Omar, A.D. 642; and it is said that, during six months, the numerous volumes supplied fuel for the 4000 baths, which contributed to the health and convenience of the populous capital of Egypt. Alexandria has likewise been distinguished for its schools, not only of theology and philosophy, but of physic, where once to have studied was a sufficient recommendation to distant countries. The astronomical school, founded by Philadelphus, maintained its superior reputation for 10 centuries, till the time of the Saracens. The modern town of Scanderoon has been erected upon the ruins of Alexandria, and, as if it were an insult to its former greatness, it scarce contains 6000 inhabitants. _Curtius_, bk. 4, ch. 8.――_Strabo_, bk. 17.――_Pliny_, bk. 5, ch. 10.――――Another in Albania, at the foot of mount Caucasus.――――Another in Arachosia, in India.――――The capital of Aria, between Hecatompylon and Bactra.――――Another of Carmania. ――――Another in Cilicia, on the confines of Syria.――――Another the capital of Margiana.――――Another of Troas, &c. _Curtius_, bk. 7.―― _Pliny_, bk. 6, chs. 16, 23, & 25. =Alexandrĭdes=, a Lacedæmonian, who married his sister’s daughter, by whom he had Dorycus, Leonidas, and Cleombrotus.――――A native of Delphi, of which he wrote a history. =Alexandrīna aqua=, baths in Rome, built by the emperor Alexander Severus.
