    • c. 37 BCE – 30 BCE, Virgil, Georgics 3.404–406:
      Nec tibi cūra canum fuerit postrēma, sed ūnā
      vēlōcis Spartae catulōs ācremque Molossum
      pāsce serō pinguī.
      Nor let the concern for your dogs be the last, but in the same way
      the brave Molossan and the whelps of the swift Spartan
      feed with fat whey.
    • c. 77 CE – 79 CE, Pliny the Elder, Naturalis Historia 28.130:
      Būbulī serum orthopnoicīs prōdest ante cētera additō nāsturtiō.
      Whey of cows is more beneficial to asthmatics than others when cress is added to it.

      Quid dīcam, Gellī, quārē rosea ista labella
           hībernā fīant candidiōra nive,
      māne domō cum exīs et cum tē octāva quiēte
           ē mollī longō suscitat hōra diē?
      Nesciŏquid certest: an vērē fāma susurrat
           grandia tē mediī tenta vorāre virī?
      Sīc certest: clāmant Victōris rupta miselli
           īlia, et ēmulsō barba notāta serō.
      What shall I say, Gellius, how these rosy lips
           are whiter than wintery snow,
      when you walk out of the house when the eighth hour
           rouses you from soft rest in the long day?
      Something's sure: perhaps your reputation whispers truthfully
           that you devour the large protuberance of a man's middle?
      So is it certain: thus the broken loins of the poor Victor
           cry, and the beard marked with the milked-out semen.
