This enclosure had a mean length of about 240 feet, with a mean breadth of 162 feet[23]. The north cloister was 37 feet broad, and was divided down the centre by a row of columns. The east cloister was of about half this width, and was undivided. On the north side of the north cloister, the German explorers found four rooms, which they believe to have been assigned to library purposes. The platform of rock on which these chambers stood was nearly 20 feet above the level of the floor of the enclosure, and they could only be entered from the upper cloister. Of these rooms the easternmost is the largest, being 42 feet long, by 49 feet broad. Westward of it are three others, somewhat narrower, having a uniform width of 39 feet. The easternmost of these three rooms is also the smallest, being only 23 feet long; while the two next have a uniform length of about 33 feet. At the south-west corner of this building, but on a lower level, and not accessible from it, other rooms were found, the use of which is uncertain. We will now return to the eastern room. The foundations of a narrow platform or bench extended along the eastern, northern, and western sides, and in the centre of the northern side there was a mass of stone-work which had evidently formed the base for a statue (fig. 2, A). The discovery of a torso of a statue of Athena[24] in this very room indicated what statue had occupied this commanding position, and also what had probably been the use of the room. This theory was confirmed by the discovery in the north wall of two rows of holes in the stone-work, one above the other, which had evidently been made for the reception of brackets, or battens, or other supports for shelves[25], or some piece of furniture. The lower of these two rows was carried along the east wall as well as along the north wall. Further, stones were found bearing the names of Herodotus, Alcaeus, Timotheus of Miletus, and Homer, evidently the designations of portrait-busts or portrait-medallions; and also, two titles of comedies. Lastly, the very position of these rooms in connexion with the colonnade indicates their use. It will be observed that the colonnade on the north side of the area is twice as wide as that on the east side--a peculiarity which is sufficient of itself to prove that it must have been intended for some other purpose than as a mere covered way. But, if it be remembered that libraries in the ancient world were usually connected with colonnades (as was probably the case at the Serapeum at Alexandria, and was certainly the case at Rome, as I shall proceed to shew) a reason is found for this dignified construction, and a strong confirmation is afforded for the theory that the rooms beyond it once contained the famous library.
