the sepulchre's second level consists of a colonnade in the form of a shrine ("naiskos"). the engaged columns on each side are of the ionic order. the third and final level is the most richly decorated: in addition to pilasters on the corners similar to those on the first level, it is capped by a pyramid. sculptural elements have survived: griffons are perched on the corners and a quadriga on one of the faces of the upper level.
