2. For the increase of knowledge. One of the chief objects of the museum was that of serving as the home of a body of men who devoted themselves to study, and were lodged and maintained at the king's expense. In the original organization of the museum the residents were divided into four faculties,—Literature, Mathematics, Astronomy, and Medicine. An officer of very great distinction presided over the establishment, and had general charge of its interests. Demetius Phalareus, perhaps the most learned man of his age, who had been Governor of Athens for many years, was the first so appointed. Under him was the librarian, an office sometimes held by men whose names have descended to our times, as Eratosthenes and Apollonius Rhodius. In connection with the museum was a botanical and a zoological garden. These gardens, as their names imply, were for the purpose of facilitating the study of plants and animals. There was also an astronomical observatory, containing armillary spheres, globes, solstitial and equatorial armils, astrolabes, parallactic rules, and other apparatus then in use, the graduation on the divided instruments being into degrees and sixths.
3. For the diffusion of knowledge. In the museum was given, by lectures, conversation, or other appropriate methods, instruction in all the various departments of human knowledge.
There flocked to this great intellectual centre, students from all countries. It is said that at one time not fewer than fourteen thousand were in attendance. Subsequently even the Christian church received from it some of the most eminent of its Fathers, as Clemens Alexandrinus, Origen, Athanasius, &c.
The library in the museum was burned during the siege of Alexandria by Julius Cæsar. To make amends for this great loss, the library collected by Eumenes, King of Pergamus, was presented by Mark Antony to Queen Cleopatra. Originally it was founded as a rival to that of the Ptolemies. It was added to the collection in the Serapion, or the temple of Serapis.[440:1]
It was not destined, however, to remain there many centuries, as this very valuable library was willfully destroyed by the Christian Theophilus, and on the spot where this beautiful temple of Serapis stood, in fact, on its very foundation, was erected a church in honor of the "noble army of martyrs," who had never existed.
This we learn from the historian Gibbon, who says that, after this library was destroyed, "the appearance of the empty shelves excited the regret and indignation of every spectator, whose mind was not totally darkened by religious prejudice."[440:2]
The destruction of this library was almost the death-blow to free-thought—wherever Christianity ruled—for more than a thousand years.
The death-blow was soon to be struck, however, which was done by Saint Cyril, who succeeded Theophilus as Bishop of Alexandria.
Hypatia, the daughter of Theon, the mathematician, endeavored to continue the old-time instructions. Each day before her academy stood a long train of chariots; her lecture-room was crowded with the wealth and fashion of Alexandria. They came to listen to her discourses on those questions which man in all ages has asked, but which have never yet been answered: "What am I? Where am I? What can I know?"
