[89] This vivarium is a triangular piece of ground, the wide end of which touches the wall of the Amphitheatrum Castrense; the narrow end is only just wide enough for the body of a man to pass through an aperture made in it, as the ground is between a wall of Aurelian on the inner side, and a wall of the Sessorium on the outer side, preserved by Aurelian as an outwork. This was the scene of the celebrated ambuscade of Belisarius, by means of which the Goths were driven away from Rome, as described by Procopius (De Bello Gothico, lib. i. c. 22.)

[93] “Ludiviæ sunt, quæ ad voluptatem oculorum atque aurium tendunt. His annumeres licet machinatores, qui pegmata per se surgentia excogitant, et tabulata tacite in sublime crescentia, et alias ex inopinato varietates, aut dehiscendentibus quæ cohærebant, aut his quæ distabant, sua sponte coeuntibus aut his quæ eminebant paulatim in se residentibus.” (Seneca, Epist., 88, s. 19.)
