Forms
perduelliō f (genitive perduelliōnis); third declension[1]
Etymology
It is formed from Latin perduellis (“public enemy”) + -iō.[2][1][3] The base is made of per- and duellum, the old form of bellum (“war”),[3][4] and de Vaan reports Meiser's view that legal language kept the ⟨du⟩ in it.[4]
The grammarian Priscian already derived it from duellum, the ancients' word for bellum;[3] Charisius took the prefix as an intensive, so that a perduellis was more than an enemy.[3]
Earliest recorded meaning
De Vaan's first author is the annalist Valerius Antias,[4] in whose history a tribune of the plebs, Licinius, fixes a day for a man's trial for it.[3] The TLL also cites it from the old royal law that Livy quotes, under which two judges try Horatius for it.[3]
Semantic evolution
It was a term of Roman criminal law, the gravest hostile act of a citizen against his own state,[2][3] such as an attack on the state, its institutions or its head, an alliance with a foreign enemy, or desertion.[5][6] Cicero spoke for Rabirius, who was charged with it,[3][7] and Livy reports cases from early Rome, among them a tribune's charge against Gnaeus Fulvius for losing an army through rashness.[3][5] After Livy it appears mostly in writers who explain the institution or recount old cases.[3] In the Digest, Ulpian says that a man accused of it acted with hostile intent against the state or the emperor.[5][3]
By metonymy the plural could mean enemies: the Rhetorica ad Herennium quotes perduelliones as an example of bombast,[6][7] and the glossary of Placidus explains the word as rebellions.[6] In British Medieval Latin it is treason, as when William of Malmesbury calls Penda, king of the Mercians, a seedbed of treasons, and Alexander Neckam uses it for the long struggle between reason and the senses.[8]
