Beowulf was a legendary heroic dragon slayer of the Geats who lived from 495–583 AD. His exploits include slaying several sea reptiles and a terrestrial dragon called a grendel. Beowulf ultimately lost his life at the age of 88 from wounds he received while fighting a flying reptile that may have been a giant pterosaur. The story of Beowulf is preserved in an epic poem of the same name that is often considered to be one of the most important pieces of Anglo-Saxon literature.

The tale of St. George and the Dragon was included in Jacobus de Voragine's Legenda Aurea (or Golden Legend), a collection of Saints' lives compiled around the year 1260 and translated into English and published by William Caxton in 1483.
A modern version of the legend says:
|“||At the town of Silene, in Libya, there was a dragon, who was appeased by being fed two sheep a day; when these failed, the townsfolk offered by lot one of their young people. One day the lot fell on the King's daughter, who was led out to the sacrifice, dressed in her wedding gown. George appeared and transfixed the dragon with his spear and then using the Princess's girdle led the bemused dragon into the town, where it was beheaded. — Catholic Encyclopaedia||”|
