The Wawel Dragon: who killed it, and what's the truth about the Dragon's Den?

What's the oldest version of the legend?

The monster makes its first written appearance around the year 1200, in the Latin chronicle of Master Vincent, Wincenty Kadłubek, Bishop of Kraków. What's striking is what he leaves out. He doesn't mention Wawel. He doesn't point to any particular cave. He places the creature among the crevices of a rock, no address given, nor does he call it a dragon. He notes, with a scholar's caution, that some people call it holophagus, a Greek name that means something like "the one who gobbles up everything".

The hero isn't who you'd expect, either. It's killed by the sons of Krak, the legendary founding king. They try taking it on face to face, and fail. So they swap strength for cunning: where the beast used to feed, they put down cattle hides packed with burning sulphur. The monster eats them, and the fire kills it from the inside. One Polish scholar thinks it likely that the earliest version had no fire-breathing at all. In this version, the fire doesn't come out of it; it goes in.

And there's no happy ending. In the chronicle, the victory sets off a run of misfortune: one brother kills the other, Krak dies, the fratricide is banished and Krak's daughter, Wanda, comes to rule.

Who put the dragon in the cave under Wawel?

Some two and a half centuries later, Jan Długosz enters the story: tutor to the princes and the great chronicler of medieval Poland. In his Annals the monster moves house and gets a new executioner. It now lives in a cave under the hill on which Krak raised his castle, looks like a dragon or a reptile, devours cattle and even people, and the townsfolk start thinking about leaving the city altogether. This time it's Krak in person who kills it, and the chronicler calls him the liberator of his homeland. He wasn't the first to give the king the credit: a 14th-century chronicle had already done so.

Did Długosz invent the cave? Not quite. Chronicles from the 13th and 14th centuries already mention a cave, even a "deep cave". What he did was give it a precise location: under the castle.

And he didn't have far to look. Długosz lived at the foot of Wawel, on Kanonicza, the street of the canons, in a house that had once been a royal bathhouse. He moved there in 1450, enlarged it, wrote his Annals there and died there in 1480. In other words, the chronicler settled the monster under the very hill next to his own front door.

Some scholars see those Annals as the moment Master Vincent's great swallower finally becomes a reptile-like dragon; others disagree.

And the shoemaker? And the sheep?

The next rewrite comes in 1551, with the first text in Polish, by Marcin Bielski. His contribution is a very riverside one: the dragon drinks from the Vistula until it bursts.

The shoemaker turns up in 1597, in a new edition prepared by Bielski's son, Joachim. And he doesn't even kill the dragon: he's the one who advises the king. His name is given as Skub, though other sources spell it Skuba. According to that chronicle, Krak has a calfskin stuffed with sulphur and left outside the cave at dawn. The dragon, which demanded three calves or rams a day, swallows it thinking it's a real calf, the sulphur smoulders inside it, and it drinks water until it dies. The shoemaker was handsomely rewarded.

And the sheep stuffed with sulphur? That came late too. One of the oldest surviving popular texts with the shoemaker as the hero is a verse pamphlet from 1849, Skub, mądry szewczyna czyli smok krakowski ("Skub, the clever shoemaker, or the Kraków dragon"). By then the bait is a sheep stuffed with sulphur and lime, and the dragon doesn't even burst: it's left so weak that the king and the shoemaker finish it off. As a reward, the shoemaker and his wife are given a title and a fortune.

Each piece was added by someone different, in a different century: the sulphur bait around 1200; the cave under the castle in the 15th century; the Vistula drink in 1551; the shoemaker, a mere adviser at first, and his calfskin in 1597; and the sheep, which we haven't found in writing before the 19th century. The legend's best-loved hero was the last to arrive.

Is it a folk tale, or did the chroniclers make it up?

No one knows for sure. Scholars are still arguing over whether Master Vincent wrote down a tale already doing the rounds in Kraków, or composed a learned story with echoes of the prophet Daniel, Alexander the Great or St George. There's no verdict, and we're not going to invent one.

Is the Dragon's Den real?

The cave certainly is. It's a karst cave, hollowed out of the hill's limestone by water over some twelve million years. It's about 270 metres long, and 81 metres of it can be visited. The visit starts at the top, by the Thieves' Tower, goes down 135 steps inside a brick tower that was once a well from the Austrian period, and comes out at the bottom on the riverside boulevard.

The first person we know went in was a historian, Ambroży Grabowski, in 1829, and he didn't use the door: he got in through a gap in the roof. In 1830 the hole was sealed with a brick dome, and thanks to his persistence the cave opened to the public between 1843 and 1846. The architect Adolf Szyszko-Bohusz fitted it out for modern visitors after 1918.

Before the visitors, the cave had some thoroughly unlegendary uses. In the 17th and 18th centuries there was a tavern on the bank of the Vistula, beside the lower entrance, which used part of the cave as a storeroom and a dining room. Until the 19th century the first chamber was flooded, and people living on the hill came down to fetch water from it. Further in, in passages closed to visitors, five small lakes are home to an unusual crustacean.

Why does the Wawel Dragon breathe fire?

Because it runs on gas. The bronze statue guarding the cave's exit dates from 1972, the work of the sculptor Chromy, and every so often it lets out a burst of flame.

The legend, by the way, is still on the move. In 2001, when the castle declared the modern belief in an energy "chakra" in a corner of its courtyard to be superstition, a magazine asked mockingly when they'd be cutting off the dragon's gas, and an ethnographer saw the chakra as a fresh twist on the old legend.

Fact or legend?

• Fact: the cave exists and is natural (some twelve million years old); Grabowski went in in 1829; there was a tavern by its mouth in the 17th and 18th centuries; the statue dates from 1972. The history of the texts is fact too: Kadłubek around 1200, Długosz in the 15th century, Bielski in 1551, the shoemaker and the calfskin in the 1597 edition, and the sheep in a popular pamphlet of 1849.
• Legend: the monster and its death, in all their variations: the sulphur, the drink from the Vistula, the shoemaker and the sheep.
• Open debate: whether the legend began in the street or at the chroniclers' desks, and whether the first monster breathed fire.

Where to hear it

The route "Wawel and the Dragon" starts right in front of the statue with the stop "The dragon's changing conquerors". The second, "The historian who came in through the roof", is heard at the cave's exit by the river. And the fifth, "The chronicler who gave the dragon an address", puts you in front of Długosz's house on Kanonicza. After that, the route climbs the hill of the kings: twelve stops in all.
