The first celebrated library of antiquity was at Alexandria, and called from thence the Alexandrian library; it owed its foundation to Ptolemy Soter, king of Egypt, though his Son Ptolemy Philadelphus enjoys the reputation of being its founder. This was about 284 years before the Christian æra. The palace of Ptolemy Philadelphus was the asylum of learned men whom he admired and patronized. He paid particular attention to Euclid, Theocritus, Callimachus, and Lycophron, and by increasing the library, of which his father had laid the foundation, he shewed his taste for learning and wish to encourage genius. This celebrated library at his death contained 200,000 volumes of the best and choicest books, and it was afterwards increased to 700,000 volumes. The method adopted for making this collection was the seizing of all the books that were brought by the Greeks or other foreigners into Egypt, and sending them to Ptolemy, who had them transcribed by persons employed for that purpose. The transcripts were then delivered to the proprietors, and the originals laid up in the library. Ptolemy Euergetes, for instance, borrowed of the Athenians the works of Sophocles, Euripides, and Æschylus, and only returned them the copies, which he caused to be transcribed in as beautiful a manner as possible; the originals he retained for his own library, presenting the Athenians with fifteen talents for the exchange, that is, with upwards of £3,000 sterling. As the Alexandrian academy was at first in the quarter of the city called _Bruchion_, the library was placed there, but when the number of books amounted to 400,000 volumes, another library within the _Serapeum_ was erected, by way of supplement to it, and on that account called the daughter of the former. The books lodged in the Serapeum increased to the number of 300,000, and these two made up the number of 700,000 volumes, of which the royal libraries of the Ptolemys were said to consist. In the war which Julius Cæsar waged with the inhabitants of Alexandria, the library of Bruchion was accidentally, but unfortunately, burned; but the library in the Serapeum still remained. The whole was magnificently repaired by Cleopatra, who deposited there the 200,000 volumes, forming the library of the kings of Pergamus, with which she had been presented by Antony. These, and others added to them from time to time, rendered the new library of Alexandria more numerous and considerable than the former, and though it was plundered more than once during the revolutions which happened in the Roman empire, yet it was as frequently supplied with the same number of books, and continued for many ages to be of great fame and use, until it was burnt by the Saracens, in the year 642 of the Christian æra.
