Bellori, Vita di Domenico Fontana. Roma, nell’ anno MDCCCXXXVIII, &c., parte i., Antica, pp. 414-417. (Le Vite de pittori, &c., Roma, 1728, 4to. p. 93.)
The space enclosed within the outer walls is six acres, and there is an extraordinary difference of climate between the northern and the southern side. Dr. Deakin published a work on the Flora of the Colosseum: he found 423 species of plants, belonging to 253 genera.
Over the door now generally used is a painting of the heavenly Jerusalem and the Crucifixion, of the time of Paul III., A.D. 1534-50, in the style of the older pilgrimage pictures. At the time it was painted the passage appears to have been filled up with earth to such a height as to make the picture a conspicuous object in leaving the building; at present it is quite above the heads of the passers-by, and is seldom noticed or seen.
