2.] Except for these, the whole edifice is perfectly plain.

Its present height above the ground is thirty-six feet, and it may originally have been a foot or eighteen inches higher, for the top of the roof is worn away.

It measures at the base forty-seven feet by forty-three feet nine inches.
The tomb stands within a rectangular area, marked out by pillars, the bases or broken shafts of which are still to be seen.

They appear to have been twenty-four in number; all of them circular and smooth, not fluted; six pillars occupied each side of the rectangle, and they stood distant from each other about fourteen feet.
