As when a lion, rushing from his den,
Amidst the plain of some wide-water'd fen,
(Where numerous oxen, as at ease they feed,
At large expatiate o'er the ranker mead)
Leaps on the herds before the herdsman's eyes;
The trembling herdsman far to           flies;
Some lordly bull (the rest dispersed and fled)
He singles out; arrests, and lays him dead.
