It is but proper that we should allude here to the fact that Mrs. Schliemann is most ably and energetically assisting her husband in the discovery of the treasures of the ancients. [Sidenote: THE SECOND TREASURY.] The dome of the Second Treasury was broken in, a long time ago, and therefore it is better known to antiquarians; but Mrs. Schliemann has now thoroughly excavated, and explored the whole building. While her husband was excavating within the walls of the Acropolis, she undertook the excavation of this relic of the past, and the approach to it, which was formerly completely concealed, is now laid bare. Its position is close to the Gate of Lions, and it is found to differ only in slight details from the other one, known as the Treasury of Athens. The lintel over the doorway is the largest stone in the building. It is twenty feet long, seven feet wide, and eighteen inches deep, and a course of large stones of the same depth is carried all around the walls, on the same level. The diameter of the dome is a little less than that of the Treasury of Athens, but as there is an opening in the top, by which the light enters, the view is not so impressive. The inhabitants of Mycenæ did not seem to be acquainted with the principle of the arch, as the dome is constructed with courses placed horizontally. Dr. Schliemann, pretending that Agamemnon was buried here, calls it the Tomb of Agamemnon; others have named it the Tomb of Cassandra. The Treasury of Athens shows the most perfect condition of building of the ancients. The second, third, and fourth treasuries (there are four in all), gradually decrease in architectural skill, and we might almost say of the fourth, that it is nothing but an excavation made in the soil, speedily covered with rough stones. It is covered in such a way that a person entering it has to creep on all fours. For what purpose these buildings were created, remains a mystery. In the Homeric age, tombs are always described as “piled,” or “heaped up;” they are always mounds, and the fact of the earth covering these so-called “treasuries,” is a strong evidence of their sepulchral character; but the magnificently built accessories would lead to the conclusion that it belongs to a period posterior to the Iliad and the Odyssey. [Sidenote: HECTOR’S TOMB.] Hector’s tomb is described as the “hollow grave.” This was the primitive cell, which became developed into an unarched dome. Of this, many examples are found in the tumuli near Kertch, some of them of a very large size, and, though different in construction, they afford a good illustrative parallel. In the structures just described, we find a developed architecture which seems to have been rich with metallic decoration. Here all resemblance to the simple cell of the hollow grave has been lost, and now the foot or two feet of earth, heaped on the top, is nearly all that is left to remind us of the original mound, from which this style of tomb had its origin.
