1822

In 1822, Percy Shelley drowned after his schooner sank in a storm off the coast of Italy. The Fourth Doctor and Sarah Jane Smith met a reprise of Shelley in Europa, who confirmed the original's birth and death years. (PROSE: Managra)

The Third Doctor and Sarah Jane met St. Nicholas in the garden of a New York City mansion. This encounter was observed by Clement C. Moore and it inspired him to write "Twas the Night Before Christmas." (PROSE: A Visit from Saint Nicholas)
