Turning to the plan (Plate I.) and to the measurements (page 37), we find the north and south faces measure 105 Greek feet, the east and west 84 feet—together, 378 feet; each angle measures across 7 ft. 6 in., and adding this 30 feet to the above, we obtain the total of 408, or 3 feet too short. This slight difference, however, is easily accounted for. That dimension is taken over the waist of the pedestals, and by allowing 4 inches for the projection of the plinth, which is a very probable amount of projection, we get the exact dimension of 411 feet we are seeking for, as measured on the upper step of the building, which is where we should naturally look for it. Not only, therefore, does this offer no difficulty, but it is a most satisfactory confirmation of all that has been urged before. CONCLUSION. On some future occasion it may be worth while to go more fully into all the minor details of this important building, and to illustrate it to a greater extent than has been attempted in this short treatise; not only because it was the building which the ancients, who ought to have been the best judges, admired most of all their architectural treasures, but because it is the one which illustrates best the principles on which their great buildings were designed. It might, therefore, be well worth while to treat it as a typical example and use it to illustrate not only the principles of Greek design in general, but more particularly to explain the doctrine of harmonic proportions in accordance with which they all were designed, and of which it is, in so far as we at present know, the most perfect example the knowledge of which has come down to our times. All that has been attempted on the present occasion is, to point out the main broad features of harmonic proportion which governed the principal dimensions of the building; but the “order” was also full of minute and delicate harmonies worthy of the most intense study. To elucidate these something more is required than a hap-hazard restoration, such as that which is found in the plates attached to Mr. Newton’s work, with the superinduced confusion of the lithographers’ inaccuracies. Every fragment requires re-examination, and every part re-measurement; but to do this requires not only unlimited access to the remains, but power to move and examine, which would not, of course, be granted, to me at least. But if it were done, and if the details were published, with the really good specimens of the sculpture, all of which are omitted from Mr. Newton’s present publication, the public might then come to understand what the Mausoleum really was, and why the ancients admired it so much.
