This article is about a phrase used on maps. For other uses, see Here be dragons (disambiguation).

"Here be dragons" means dangerous or unexplored territories, in imitation of a supposed medieval practice of putting dragons, sea serpents and other mythological creatures in uncharted areas of maps.[1]

History

<templatestyles src="Template:Quote_box/styles.css" />

As geographers, Sosius, crowd into the edges of their maps parts of the world which they do not know about, adding notes in the margin to the effect, that beyond this lies nothing but sandy deserts full of wild beasts, unapproachable bogs, Scythian ice, or a frozen sea, so, in this work of mine, in which I have compared the lives of the greatest men with one another, after passing through those periods which probable reasoning can reach to and real history find a footing in, I might very well say of those that are farther off, beyond this there is nothing but prodigies and fictions, the only inhabitants are the poets and inventors of fables; there is no credit, or certainty any farther.

Plutarch, Parallel Lives (1st century)

There are just two known historical uses of this phrase in the Latin form "HIC SVNT DRACONES" (i.e. hic sunt dracones, 'here are dragons'). One is on the Hunt-Lenox Globe[1] (c. 1503–07), on which the term appeared around the east coast of Asia. This might be related to the Komodo dragons on the Indonesian islands, tales of which were quite common throughout East Asia.[2] The other appearance of the term is on a globe engraved on two conjoined halves of ostrich eggs, dated to 1504.[3] Earlier maps contain a variety of references to mythical and real creatures, but the Lenox Globe and the egg globe are the only known surviving maps to bear this phrase. Furthermore, the two maps may be closely linked: an investigation of the egg globe performed by collector Stefaan Missinne concluded that the Hunt-Lenox Globe is in fact a cast of it. "'Here be dragons,' [is] a very interesting sentence," said Thomas Sander, editor of the Portolan, the journal of the Washington Map Society. "In early maps, you would see images of sea monsters; it was a way to say there's bad stuff out there."[3]

The classical phrase used by ancient Roman and Medieval cartographers was HIC SVNT LEONES (literally, Here are lions) when denoting unknown territories on maps.

Dragons on maps

The 1265 Psalter world map

Dragons appear on a few other historical maps.

  • The T-O Psalter world map (c. 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 (c. 1430), 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 there are even men who have large four-foot horns, and there are even serpents so large that they could eat an ox whole.").
  • The Fra Mauro Map (c. 1450) has the "Island of Dragons" (Italian: Isola de' dragoni ), an imaginary island in the Atlantic Ocean.[4] In an inscription near Herat, Fra Mauro says that in the mountains nearby "there are a number of dragons, in whose forehead is a stone that cures many infirmities", and describes the locals' way of hunting those dragons to get the stones. This is thought to be based on Albertus Magnus's treatise De mineralibus.[5] In an inscription elsewhere on the map, the cartographer expresses his skepticism regarding "serpents, dragons and basilisks" mentioned by "some historiographers".[6]
  • A 19th-century Japanese map, the Jishin-no-ben, in the shape of Ouroboros depicts a dragon associated with causing earthquakes.

Computer science

In computer programming, software programmers sometimes use this expression to indicate sections of particularly complex and obscure passages of the source code of a program so the user or other programmers who would access them are warned. The fragment of code can be particularly complex because of the application needs, or because it has not been written clearly enough.

The metaphor of an explorer who passed this limit, must act wisely with care and skillfully before continuing, reflects reality as some programmers prefer to avoid this code, while the more adventurous, or those looking for challenges, prefer to explore and perhaps clarify (document or "map") these code areas for others.

For example, in version 3.5 of the Mozilla Firefox browser, this sentence appears when the user types "about: config" in the address bar, opening the configuration of the browser environment.

Other creatures on maps

  • Ptolemy's atlas in Geographia (originally 2nd century, taken up again in the 15th century) warns of elephants, hippos and cannibals.
  • Tabula Peutingeriana (medieval copy of Roman map) has "in his locis elephanti nascuntur", "in his locis scorpiones nascuntur" and "hic cenocephali nascuntur" ("in these places elephants are born, in these places scorpions are born, here Cynocephali are born").
  • 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 rather fertile, but on the other hand it is full of beasts and serpents.")
  • The Ebstorf map (13th century) has a dragon in the extreme south-eastern part of Africa, together with an asp and a basilisk.
  • Giovanni Leardo's map (1442) has, in southernmost Africa, "Dixerto dexabitado p. chaldo e p. serpent".
  • 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.
  • On the maps surrounding Imperialism, up until the Berlin Conference of 1885 and the discoveries made by Livingstone, elephants were drawn in as is shown by this small poem by Jonathan Swift, "So geographers, in Afric maps, With savage pictures fill their gaps, And o'er uninhabitable downs, Place elephants for want of towns."
