Annus Mirabilis is a poem written by John Dryden published in 1667. It commemorated 1665–1666, the "year of miracles" of London. Despite the poem's name, the year had been one of great tragedy, including the Great Fire of London. The title was perhaps meant to suggest that the events of the year could have been worse. Dryden wrote the poem while at Charlton in Wiltshire, where he went to escape one of the great events of the year: the Great Plague of London. Source: Wikipedia (en)
