Procedunt, gemini ceu foedere iuncto
hiberna sub nocte lupi: licet et sua pulset
natorumque fames, penitus rabiemque minasque
dissimulant humilesque meant, ne nuntiet hostes
cura canum et trepidos moneat vigilare magistros.
(Statius, Ach. 1.704-708)
They go forward like two wolves in league on a winter’s night; though hunger, their own and their cubs’, pushes them, they quite dissemble their ravening threats and move meekly, lest watchdogs announce the enemy and warn the fearful shepherds to keep vigil. (tr. David Roy Shackleton Bailey)
