As when a bull, whom galling gadflies wound,
Forsakes the meadows, and the marshy ground,
The flowery food, the herd and herdsmen shuns,
Now stands stock-still, and restless now he runs;
Stung by the breese, he maddens with the pain,
Tosses aloft his head, and roars amain.
Lines 1626–1631 - Argonautica (3rd century BC) - Book I
