ancient city, that the platform is cut like a step in
the base of a conical hill to the north. This hill is
of volcanic origin; the rock, of which its base is
composed, and which has served as a quarry before
the building of the Mausoleum, has been pronounced
by competent mineralogical authority, to be a
calcareous tufa, in which volcanic materials are
cemented together.

To the north of the road beyond the north wall
of the peribolus, the original features of the quarry
are quite distinct. The rocky slopes of the hill,
nearly to its summit, are cut into vertical faces,
with monolithic chambers and graves at intervals,
the position of which is marked in Plate I.
