The interior walls of this Treasury have never been covered with brazen plates like the Treasury of Atreus here and the Treasury of Minyas in Orchomenus; at least, I see nowhere in the stones the holes of the bronze nails by which the metal plates were fastened; but I cannot avoid mentioning that on the inner east side of the Treasury, there protrudes from between the stones the fragment of a bronze plate, which sticks so fast that it cannot be drawn out; I therefore suppose that it was fastened there when the Treasury was built. It appears hardly possible that this could have happened merely by accident, but on the other hand I find it difficult to believe that this bronze plate could be a remnant of an ancient wall-coating of bronze plates, which were not fastened to the stones with nails but were attached in the joints between them, because in this case, I presume, we ought to find remnants of those plates in many places. This Treasury is less sumptuous, and appears to be more ancient, than the Treasury of Atreus here, or the Treasury of Minyas at Orchomenus. The entrance, which is 13 ft. long and 8 ft. broad, is roofed with four slabs 18½ ft. in length; the holes for the upper door-hinges are 5 in. deep. From certain traces in the walls it appears that the entrance has been ornamented on the right and left with two semi-columns, which we hope to find by digging deeper. A remnant of an ornamentation with semicircles is visible on the slab above the entrance, and the same can easily be distinguished in the engraving of the Treasury.[227] After having been buried for ages in the damp _débris_, the large wrought stones of the walls of the approach (_dromos_) and of the façade of this Treasury have contracted by exposure to the sun, and, as may be seen from the engraving, a great number of them have crevices. As in the Treasury of Atreus and in the Lions' Gate, the triangular space above the entrance is formed by an oblique approximation of the ends of the courses of stone. On all three sides of this triangle can be seen cuttings, which make it highly probable that it has once been filled up by a triangular piece of sculpture similar to that above the Lions' Gate.[228]
