## HISTORY, PURPOSE AND USAGE

Lorem ipsum, or lipsum as it is sometimes known, is dummy text used in laying out print, graphic or web designs. 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. It usually begins with:

## HEDONIST ROOTS

Until recently, the prevailing view assumed lorem ipsum was born as a nonsense text. “It's not Latin, though it looks like it, and it actually says nothing,” Before & After magazine [answered a curious reader](https://www.straightdope.com/columns/read/2290/what-does-the-filler-text-lorem-ipsum-mean/), “Its ‘words’ loosely approximate the frequency with which letters occur in English, which is why at a glance it looks pretty real.”

**As Cicero would put it, “Um, not so fast.”**

The placeholder text, beginning with the line “Lorem ipsum dolor sit amet, consectetur adipiscing elit”, looks like Latin because in its youth, centuries ago, it was Latin.

Richard McClintock, a Latin scholar from **Hampden-Sydney College**, is credited with discovering the source behind the ubiquitous filler text. In seeing a sample of lorem ipsum, his interest was piqued by consectetur—a genuine, albeit rare, Latin word. Consulting a Latin dictionary led McClintock to a passage from De Finibus Bonorum et Malorum (“On the Extremes of Good and Evil”), a first-century B.C. text from the Roman philosopher Cicero.

In particular, the garbled words of lorem ipsum bear an unmistakable resemblance to sections `1.10.32–33` of Cicero's work, with the most notable passage excerpted below:

McClintock's eye for detail certainly helped narrow the whereabouts of lorem ipsum's origin, however, the “how and when” still remain something of a mystery, with competing theories and timelines.

## Creation timelines for the standard lorem ipsum passage vary, with some citing the 15th century and others the 20th.

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.

- It's difficult to find examples of lorem ipsum in use before Letraset made it popular as a dummy text in the 1960s, although McClintock says he remembers coming across the lorem ipsum passage in a book of old metal type samples. So far he hasn't relocated where he once saw the passage, but the popularity of Cicero in the 15th century supports the theory that the filler text has been used for centuries.
- And anyways, as Cecil Adams reasoned, “[Do you really] think graphic arts supply houses were hiring classics scholars in the 1960s?” Perhaps. But it seems reasonable to imagine that there was a version in use far before the age of Letraset.
