Other forms: epigraphs
An epigraph is an engraved inscription on a building or statue, or a quotation at the beginning of a piece of writing.
If you look on the U.S. government minted coins in your pocket, you'll see the epigraph "In God We Trust." Epigraph comes from the Greek roots epi- ("on") and graphein ("write"), a root you'll recognize from autograph, graphite, graphic novel, and lots of other familiar words that have to do with writing or drawing.
