The Wawel Dragon (), also known as the Dragon of Wawel Hill, is a famous dragon in Polish legend. According to the earliest account (13th century), a dragon (, "one who swallows whole") plagued the capital city of Kraków established by legendary King Krak (or Krakus, Gracchus, etc.). The man-eating monster was being appeased with a weekly ration of cattle, until finally defeated by the king's sons using decoy cows stuffed with sulfur. But the younger prince ("Krak the younger" or "Krak junior") murdered his elder brother to take sole credit, and was banished afterwards. Consequently Princess Wanda had to succeed the kingdom. Later in a 15th-century chronicle, the prince-names were swapped, with the elder as "Krak junior" and the younger as Lech. It also credited the king himself with masterminding the carcasses full of sulfur and other reagents. A yet later chronicler (Marcin Bielski, 1597) credited the stratagem to a cobbler named Skub (Skuba), adding that the "Dragon's Cave" () lay beneath Wawel Castle (on Wawel Hill on the bank of the Vistula River). Literary history The oldest known telling of the story comes from the 13th-century work attributed to Bishop of Kraków and historian of Poland, Wincenty Kadłubek. Polish Chronicle (13 c.) According to Wincenty Kadłubek's Polish Chronicle, a dragon appeared during the reign of King Krak (, ). St. Wincenty's original Latin text actually refers to the dragon as holophagus (Polish gloss: ; "one who swallows whole"), which was a neologism he had coined. In Polish translation of the work, the monster is rendered as the "greedily swallowing dragon" (). It was a "terrible and cruel beast" dwelling "in the depths [windings/curves] of a certain rock ()" or emended to "a certain cave ()" according to Wincenty. The dragon required weekly cattle, or else humans would have been devoured instead. In the hope of killing the dragon, Krak called upon his two sons. They could not, however, defeat the creature by hand, so they came up with a trick. They fed him a cattle skin stuffed with smoldering sulfur, causing his fiery death. After the success, the younger prince (referred to as the "junior Graccus"; var. , i.e. Krak II; ) kills his elder brother blaming the dragon for the death. But his crime was soon revealed, and he got expelled from the country. Afterwards Princess Wanda had to accede the kingship. Derivative chronicles Among later chronicles
