Note 246 — THE COLOSSEUM. PLATE IX.

The photo-engraver has unfortunately turned this photograph upside down, but it is not of much consequence, as the size and thickness of the bricks of Nero can be seen just the same. The space is so narrow that it was difficult to get a photograph of it at all; but this is just one of the cases in which a photograph is of great importance, because there is nothing in which artists are so careless as in the thickness of the bricks and of the mortar between them; there is nothing in which it would be more easy to play tricks, if they wished to do so.
