Most of its text is made up from sections 1.10.32–3 of Cicero’s De finibus bonorum et malorum (On the Boundaries of Goods and Evils; finibus may also be translated as purposes). Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit is the first known version (“Neither is there anyone who loves grief itself since it is grief and thus wants to obtain it”). It was found by Richard McClintock, a philologist, director of publications at Hampden-Sydney College in Virginia; he searched for citings of consectetur in classical Latin literature, a term of remarkably low frequency in that literary corpus.
Cicero famously orated against his political opponent Lucius Sergius Catilina. Occasionally the first Oration against Catiline is taken for type specimens: Quo usque tandem abutere, Catilina, patientia nostra? Quam diu etiam furor iste tuus nos eludet? (How long, O Catiline, will you abuse our patience? And for how long will that madness of yours mock us?)
