The method of roofing is therefore identical in principle
with that used in the galleries and store chambers of
Tiryns; but here the blocks have been much more carefully
worked and accurately fitted, and the exposed ends have been
so beveled as to give to the whole interior a smooth, curved
surface. Numerous horizontal rows of small holes exist, only
partly indicated in our illustration, beginning in the
fourth course from the bottom and continuing at intervals
probably to the top. In some of these holes bronze nails
still remain. These must have served for the attachment of
some sort of bronze decoration. The most careful study of
the disposition of the holes has led to the conclusion that
the fourth and fifth courses were completely covered with
bronze plates, presumably ornamented, and that above this
there were rows of single ornaments, possibly rosettes. Fig.
27 will give some idea of the present appearance of this
chamber, which is still complete, except for the loss of the
bronze decoration and two or three stones at the top. The
small doorway which is seen here, as well as in Fig. 26,
leads into a rectangular chamber, hewn in the living rock.
This is much smaller than the main chamber.
