"Unknown Land" on Old Maps
The Latin phrase *terra incognita* meant unknown land. Cartographers sometimes left areas blank or decorated maps with ships and fantastical sea creatures. Such imagery was not a standard feature of every map: the Library of Congress notes that monsters appeared more often on decorative maps than on practical nautical charts.
The famous inscription “Here be dragons” (*Hic sunt dracones*) is genuinely rare. The New York Public Library identifies only two known medieval or Renaissance maps or globes bearing the phrase. It is therefore a vivid modern shorthand for unknown territory, but not a label routinely used by mapmakers to fill blank spaces.
