The word was very rare in Classical Latin:[4] besides Accius, only Cicero has it, in the second Philippic, with incredibilis, “unbelievable stupidity”.[4][5] Later it appears in Arnobius, Nonius Marcellus and Eugraphius.[1][5] From Latin it passed into English as stupidity and into German as Stupidität.[1][6]
