But I could have easily vindicated humankind from the imputation of singularity upon the last article, if there had been any swine in that country (as unluckily for me there were not), which, although it may be a sweeter quadruped than a Yahoo, cannot, I humbly conceive, in justice, pretend to more cleanliness; and so his honour himself must have owned, if he had seen their filthy way of feeding, and their custom of wallowing and sleeping in the mud.

Within the court, around their father, sat His sons, their raiment all bedew'd with tears; And in the midst, close cover'd with his robe, Their sire, his head and neck with dirt defil'd, Which, wallowing on the earth, himself had heap'd, With his own hands, upon his hoary head.
Homer -- The Iliad
