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, (TV: The Woman Who Lived) a 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 repair kit. (TV: The Girl Who Died)
