The Lambton Worm

The tale of the Lambtom Worm comes from Britain near the times of the Crusades. It recounts a tale that lasts for the lifetime of one John Lambton, a nobleman. When young, he caught a vicious and noisome black creature when fishing one day. Despite warnings from a mysterious stranger, he threw the creature into the village well.
John Lambton went off to fight in the crusades and the creature grew and took to eating sheep and destroying cows to get at the milk. The villagers began to offer it daily feasts of milk to appease its hunger. Many tried to destroy it, but were all killed.
At long last, when John Lambton retured from the wars, he vowed to kill the dragon. Using a specially-made armor with many spikes, he confronted the beast on its island rock. Whenever it attacked, it injured itself on the spiky armor and, eventually, John Lambton was able to dispatch it.

St. George and the Dragon
The tale of St. George and the dragon is essentially a legend about the spread of Christianity through Europe and Britain. St. George is now considered the patron saint of England who lived in the third and fourth centuries AD.
The legend tells of a horrible dragon beast who lived in a well in a town in Libya and needed to be appeased with sheep and maidens. The people were held captive by this dragon in the need to feed it. The young women of the area drew lots to see who would offer herself up to the dragon next.
When the princess was chosen to be the dragon’s next meal, St. George sprang into action and galloped off to slay the beast. After having subdued the dragon, he paraded it through the town and only agreed to slay it after thousands converted to Christianity.
Tiamat: Babylonia Creation

Tiamat is one of the original players in the Babylonian creation myth. She has been described as both a dragon-like creature and a large snake form, often with front legs. She was the embodiment of the sea and, together with Apsu, fresh water, formed the whole of creation before the gods were born.
Legend has it that the gods, most especially Marduk, stifled Tiamat with the winds and weather and thus beat down her chaotic nature to create order in the world.
