The new city which for centuries was the intellectual and commercial storehouse of Europe, Africa and India, was of oblong form. Lake Mareotis washed its walls on the south, while the Mediterranean bathed its ramparts on the north. Provided with broad streets, it was adorned with magnificent houses, temples and public buildings. At the centre of the city was the Mausoleum in which was deposited the body of Alexander, embalmed after the manner of the Egyptians. Alexandria was divided into three parts: the _Regio Judaeorum_ or Jews’ quarter, in the northwest; the _Rhacotis_, or Egyptian section, on the west, containing the Serapeum with a large part of the Library; and on the north, the _Bruchaeum_, or Greek portion, containing the greater part of the Library, the Museum, the Temple of the Caesars and the Court of Justice. The population was cosmopolitan in character; the statues of the Greek gods stood by the side of those of Osiris and of Isis; the Jews forgot their language and spoke Greek; and under the Ptolemies, who were of Greek descent, Alexandria became a centre of intellectual life and culture. To the medical historian the most interesting feature of Alexandria was the Museum or University. Here were assembled the intellectual giants of the earth: Archimedes and Hero, the philosophers; Apelles, the painter; Hipparchus and Ptolemy, the astronomers; Euclid, the geometer; Eratosthenes and Strabo, the geographers; Manetho, the historian; Aristophanes, the rhetorician; Theocritus and Callimichus, the poets; and Erasistratus and Herophilus, the anatomists, all of whom labored in quiet upon the peaceful banks of the Nile. The early Christian church drew from “the divine school at Alexandria” such eminent teachers as Origen and Athanasius. Here were a chemical laboratory, a botanical and zoölogical garden, an astronomical observatory, a great library, and a room for the dissection of the dead. In the Alexandrian school of medicine Erasistratus and Herophilus taught the science of organization from actual dissections. The generosity of the Ptolemies not only furnished them with an abundance of dead material, but condemned malefactors were used for human vivisection. Celsus[5] states that the Alexandrian anatomists obtained criminals, “for dissection alive, and contemplated, even while they breathed, those parts which nature had before concealed.”
