This appears to have also occurred to two of Alexander's lieutenants--one Eumenes, Governor of Pergamos, and the other, Ptolemy, Governor of Egypt. After the death of the conqueror his generals shook of all dependence upon the central government, and endeavored to centralize their own authority. But these two were the only ones among so many leaders who did not devote all their attention to armies and invasion, but interested themselves in commerce and arts. So active were they in the enterprise that Eumenes had gathered two hundred thousand volumes for the library at Pergamos, and Ptolemy six to seven hundred thousand for that of Alexandria. The latter was divided{ 031} into two parts, the greater and the lesser, the latter of which was kept in the temple of Serapis, hence known as the _Serapium_. These notable efforts to found enormous collections first excited praiseworthy rivalry among contemporaries and rulers, which, however, degenerated into contemptible jealousy, so that some of the rulers of Alexandria even went so far as to interdict the exportation of papyrus, in order to prevent the making of copies for the library of Pergamos. But the effect was unexpected, since it led to the invention of the paper of Pergamos, otherwise called parchment, which completely displaced the bark from which papyri were made. Be this as it was, the collection at Alexandria had a much more marked influence on the medical study of the future than that of Pergamos, and calls for our particular notice. About it sprang up first a collection of learned men, and then the inevitable result--a school of learning. It was Ptolemy Soter who called around him the most renowned men of his day. He provided them with homes adjoining the library, endowed them with salaries, and charged them with the classification and collation of manuscripts, or with the giving of instruction by lectures and discussions. Ptolemy himself sometimes took part in these feasts of reason, which became still more frequent and formal under his son Ptolemy Philadelphia. These were called the Feasts of the Muses and of Apollo,--_i.e., ludi musarum_,--and, consequently, the place where they were held came to be termed the "_museum_." Often the subjects for discussion were announced in advance, and those who gained the most applause received rewards in accordance with the merits of their work. Among those who enjoyed these advantages under the reign of these two Ptolemies are prominently named two physicians, Herophilus and Erasistratus, the latter said to be the grandson of Aristotle. It was under this Philadelphus that the Hebrew wise men translated into Greek the Holy Scriptures, which translation has since{ 032} been called the Septuagint--so called because it is supposed to have been translated by the members of the Sanhedrim, which was composed of about seventy men, or because, according to another legend, it was translated by seventy-two men in seventy-two hours. These _savants_ of ancient Egypt, thus supported by the dynasty of the Lagides, gave the first place to the science of medicine. As regards this study, the school of Alexandria eclipsed almost from its origin the ancient schools of Cos and Pergamos, and during its existence was the leading institution of its kind in the world. At the time of Galen it was sufficient to have studied there, and even to have resided a short time in Alexandria, to obtain the reputation of being a physician. Nearly all the scholars of these five centuries had received instruction in this school. The principal reason for its eminence in medical instruction was the practice of dissection of human bodies, which, under the Ptolemies, was allowed and recommended, and by which the science of medicine received an extraordinary impulse. Although the prejudice of Egyptians was very strong against those who touched a dead body, the Ptolemies themselves are said to have participated in this kind of anatomical study, thus destroying by their example the odium previously attached to dissection. Strange to say, however, the practice of dissection fell into disuse toward the end of this Anatomic Period, and scholars preferred to indulge in subtle metaphysical discussions rather than study human tissues. But the principal reason for giving up this practice was the Roman domination of Egypt, the Romans, inconsistently, being perfectly willing to see any amount of bloodshed in the arena, and all sorts of inhumanities practiced upon living human beings, but holding that contact with a corpse was profanation; so that not a single anatomist of reputation had his origin in ancient Rome.
