14th century

The 14th century was not a century visited often by the Doctor and his companions.

At some point in the century, the Second Doctor, Jamie and Victoria went to Ireland. (PROSE: Screamager) At another point, according to the mysterious woman who once appeared to Wilfred Mott, a "demon" fell from the sky near a convent, only to be defeated by a man in a blue box called the "Sainted Physician". (TV: The End of Time) Towards the beginning of the century, the Ninth Doctor, Rose and Jack visited Kyoto. (TV: Bad Wolf)

Late in the century, Europeans invented wire-drawing machines. (TV: The Masque of Mandragora)

It was also among the centuries endured by Ashildr, later known as "Lady Me", an 9th century Viking girl who was rendered effectively immortal when she was brought back to life by the Twelfth Doctor through a self-repairing Mire medical kit. (TV: The Woman Who Lived)
