           But it is of special effect for the spleen, if its juice, squeezed out, is drunk in wine. So extraordinary do they make out its antipathy against this specific organ to be, that they affirm that if pigs drink from troughs made out of it, they'll be found without a spleen.

         • c. 27 CE – 66 CE, Petronius, Satyricon 66:

         • 29 BCE – 19 BCE, Virgil, Aeneid 6.411–414:

           Then the other souls, sitting on the long thwarts, he routs out and clears the gangways; at once he takes in the ship the giant Aeneas. The seamy boat creaks under the weight and, full of fissures, takes marshy water in.

        The soul is thrilled to now see, first, luxurious young men, acquaintances of a rich and well-known woman, and second, strong men posted by their commandress in the ambush and garrison of the baths; for which I'd ask, how did they hide and where, and whether that was a bathtub or a Trojan Horse, which carried and hid so many invincible men fighting a war for a woman.
