Here be dragons

"Here be dragons" is a phrase used to denote dangerous or unexplored territories, in imitation of the medieval practice of putting sea serpents and other mythological creatures in blank areas of maps.

History
The only known use of this phrase is in the Latin form "HC SVNT DRACONES" (i.e. hic sunt dracones) on the Lenox Globe (ca. 1503-07). The term appeared on the east coast of Asia. Earlier maps contain a variety of references to mythical and real creatures, but the Lenox Globe is the only known surviving map to bear this phrase. The classical phrase utilized by ancient Roman and Medieval cartographers used to be HIC SVNT LEONES (literally, Here are lions) when denoting unknown territories on maps.

Dragons on maps
Dragons appear on a few other historical maps.


 * The T-O Psalter map (ca. 1250 AD) has dragons, as symbols of sin, in a lower "frame" below the world, balancing Jesus and angels on the top, but the dragons do not appear on the map proper.
 * The Borgia map (ca. 1430 AD), in the Vatican Library, states, over a dragon-like figure in Asia (in the upper left quadrant of the map), "Hic etiam homines magna cornua habentes longitudine quatuor pedum, et sunt etiam serpentes tante magnitudinis, ut unum bovem comedant integrum." ("Here, indeed, are men who have large horns of the length of four feet, and there are even serpents so large, that they could eat an ox whole.") The latter may refer to the dragons of the Chinese dragon dance.
 * A 19th-century Japanese map, the Jishin-no-ben, depicts a dragon associated with causing earthquakes.

 * Cotton MS. Tiberius B.V. fol. 58v (10th century), British Library Manuscript Collection, has "hic abundant leones" ("here lions abound"), along with a picture of a lion, near the east coast of Asia (at the top of the map towards the left); this map also has a text-only serpent reference in southernmost Africa (bottom left of the map): "Zugis regio ipsa est et Affrica. est enim fertilis. sed ulterior bestiis et serpentibus plena" ("This region of Zugis is in Africa, it is truly fertile, however it is full of beasts and serpents.")

 * Martin Waldseemüller's Carta marina navigatoria (1516) has "an elephant-like creature in northernmost Norway, accompanied by a legend explaining that this 'morsus' with two long and quadrangular teeth congregated there", i.e. a walrus, which would have seemed monstrous at the time.
 * Waldseemüller's Carta marina navigatoria (1522), revised by Laurentius Fries, has the morsus moved to the Davis Strait.
 * Bishop Olaus Magnus's Carta Marina map of Scandinavia (1539) has many monsters in the northern sea, as well as a winged, bipedal, predatory land animal resembling a dragon in northern Lapland.
