Cf. Virgil, Aen. xi. 492:—

Qualis ubi abruptis fugit praesepia vinclis

Tandem liber equus, campoque potitus aperto

Aut ille in pastus armentaque tendit equarum,

Aut adsuetus aquae perfundi flumine noto

Emicat, arrectisque fremit cervicibus alte

Luxurians, luduntque jubae per colla, per armos.

[47] 'They watch, as when the consul is going to give the signal, all look eagerly to the barrier, to see how soon he may start the chariots from the painted entrance.'

[48]

Olli subridens hominum sator atque deorum
