The Laidly Worm of Spindleston Heugh

In the Kingdom of Northumbria, a kind king in Bamburgh Castle takes a beautiful but cruel witch as his queen after his wife's death.

The enchantment used is usually: Later in the story, the prince returns and, instead of fighting the dragon, kisses it, restoring the princess to her natural form.

[1][2] In Joseph Jacob's version, the dragon Princess Margaret is appeased by putting aside seven cows for her per day.

According to a local legend, Child Wynd threw his horse's bridle over the rock before tackling the worm.

Percy had embarked on a British Empire-spanning project to collect all the oral and written lore and ballads, which he assembled into a volume called Reliques of Ancient English Poetry.
