Note 181 — Chapter IV · BASILICAS, THEATRES, AND BATHS.

Considerable difference of opinion seems to exist as to the extent of the velaria which sheltered the arena; this was supported by masts fixed outside the upper part of the walls, resting on brackets, 14 ft. below the cornice, which was cut away to allow the mast to fit close against the wall. M. Gérôme suggests, in his well-known picture of the Roman gladiators, that the velaria extended over a portion of the arena only. Prof. Middleton states, “The awning did not, as has been sometimes supposed, cover the whole amphitheatre, a thing which would have been practically impossible, owing to the enormous strain of so long a bearing, far beyond what any ropes could bear. It simply sloped down over the spectators in the cavea, leaving the whole central arena uncovered.” In case of rain, however, this might have been inconvenient, and it would not have protected the spectators from the sun, supposing that the performances lasted the whole day. Besides, there is no reason why the masts should have been carried so high above the wall, as shown in the restoration in Prof. Middleton’s book, p. 70. Mr. Alma Tadema is of opinion that the velarium extended over the whole arena, and was suspended on a principle similar to that of a suspension bridge, the ridge, or highest portion lying between the foci of the ellipse. This accounts in a much more satisfactory way for the height of the masts, and would afford facilities for the draining off of the rain on to the top of the gallery round.
