There is a book thus titled (the one who wrote it [is] Athenaeus by name) which is helpful. [It records] that Ulpian, one of the Dinner-Sophists, who was called "Attested-or-Unattested" [Keitoukeitos] because of his constantly challenging whether "hour" is attested for any part of the day; and whether "drunk" [is attested] for a male; whether "womb" was applied to edible food; and whether "wild swine" is attested for the pig. And he had a personal habit of tasting nothing before he had said whether it was attested or unattested.[1]
"Attested-or-Unattested" [Keitoukeitos]: look in the [entry] "Athenaeus" [the section] concerning the ancient men he mentions, whose generous fashion of entertaining was renowned, [as] about Alexander and Alcibiades and Empedocles of Akragas and the rest.[2]
