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, Alcæus, 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.
When the Romans had taken possession of Pergamon, those who had charge of the city would become familiar with the library; and it seems to me almost certain that, when the necessity for establishing a public library at Rome had been recognised, the splendid structure at Pergamon would be turned to as a model. But, if I mistake not, Roman architecture had received an influence from Pergamon long before this event occurred. What this was I will mention presently.
No public library was established in Rome until the reign of Augustus. Julius Cæsar had intended to build one on the largest possible scale, and had gone so far as to commission Varro to collect books for it[26]; but it was reserved for C. Asinius Pollio, general, lawyer, orator, poet, the friend of Virgil and Horace, to devote to this purpose the spoils he had obtained in his Illyrian campaign, b.c. 39. In the striking words of Pliny "he was the first to make men's talents public property (ingenia hominum rem publicam fecit)" The same writer tells us that he also introduced the fashion of decorating libraries with busts of departed authors, and that Varro was the only living writer whose portrait was admitted[27]. Pollio is further credited, by Suetonius, with having built an atrium libertatis[28], in which Isidore, a writer of the seventh century, probably quoting a lost work of Suetonius, places the library, with the additional information, that the collection contained Greek as well as Latin books[29].
The work of Pollio is recorded among the acts of generosity which Augustus suggested to others. But before long the emperor turned his own attention to libraries, and enriched his capital with two splendid structures which may be taken as types of Roman libraries,—the library of Apollo on the Palatine Hill, and that in the Campus Martius called after Octavia, sister to the emperor. I will take the latter first.
The Porticus Octaviæ, or, as it was sometimes called, the Opera Octaviæ, must have been one of the most magnificent structures in Rome ([fig. 3]). It stood in the Campus Martius, near the Theatre of Marcellus, between the Capitoline Hill and the Tiber. A double colonnade surrounded an area which measured 443 feet by 377 feet, with Jani, or four-faced archways, at the four corners, and on the side next the Tiber a double hexastyle porch, which, with a few fragments of the colonnade, still exists in a fairly good state of preservation[30]. Within this space were two temples, one of Jupiter, the other of Juno, a curia or hall, in which the Senate frequently met, a schola or "Conversation Hall[31]," and two libraries, the one of Greek, the other of Latin books. The area and buildings were crowded with masterpieces in bronze and marble.
This structure was originally built by Quintus Metellus, about 146 b.c.[32]. One of the temples was due to his own liberality, the other had been erected by Domitius Lepidus, b.c. 179. Now twenty years before, Metellus had fought in a successful campaign against Perseus king of Macedonia, in which the Romans had been assisted by Eumenes II.: and in b.c. 148, as Prætor, he received Macedonia as his province. Is it not possible that on one or other of these occasions he may have visited Pergamon, and, when designing his buildings in Rome, have copied what he had seen there? Again, in b.c. 157, Crates of Mallus, a distinguished grammarian, was sent from Pergamon as ambassador to Rome, and, being laid up there by an accident, gave lectures on grammar, in the course of which he could hardly have failed to mention the new library[33].
