Lucretius, On the Nature of Things
1.404-409 (tr. W.H.D. Rouse, rev. Martin F. Smith):
For as hounds very often find by their scent the leaf-hidden resting-place of the mountain-ranging quarry, when once they have hit upon certain traces of its path, so will you be able for yourself to see one thing after another in such matters as these, and to penetrate all unseen hiding-places, and draw forth the truth from them.
namque canes ut montivagae persaepe ferai
naribus inveniunt intectas fronde quietes, 405
cum semel institerunt vestigia certa viai,
sic alid ex alio per te tute ipse videre
talibus in rebus poteris caecasque latebras
insinuare omnis et verum protrahere inde.
404 ferai Q corr.: ferare OQ: ferarum O corr.
