The passage is attributed to an unknown typesetter in the 15th century who is thought to have scrambled parts of Cicero’s De Finibus Bonorum et Malorum for use in a type specimen book. So how did the classical Latin become so incoherent? According to McClintock, a 15th century typesetter likely scrambled part of Cicero’s De Finibus in order to provide placeholder text to mockup various fonts for a type specimen book. But it seems reasonable to imagine that there was a version in use far before the age of Letraset.
