[Meaning something] appropriate to a pig, the work of a swine. It is said that Socrates, in the presence of many others and Euthydemus himself, said that "Critias might seem to suffer from something swinish, wanting to rub himself against Euthydemus, just like piglets [do] against stones." Xenophon says [this].[1]
[sc. Also attested is the phrase] 'of swinish creatures':[2] "and this seemed to me not a human [condition], but rather to be that of certain swinish creatures." Plato [sc. says this] in Laws [book] 7.[3]
[sc. Also attested is] 'you are acting the pig': "when you talk of pigs and dog-headed people,[4] you are not only acting the pig yourself, but you are not acting finely in persuading your hearers to do so toward my writings”. Plato [sc. says this] in Theaetetus.[5]
