De nugis curialium (Medieval Latin for "Of the trifles of courtiers") is the major surviving work of the 12th century Latin author Walter Map. He was an English courtier of Welsh descent, probably born in Herefordshire, whose studies and employment took him to Canterbury, Paris, Rome and to several royal and noble courts of western Europe. The book takes the form of a series of anecdotes of people and places, offering many sidelights on the history of his own time. Some are from personal knowledge, and apparently reliable; others represent popular rumours about history and current events, and are often far from the truth.
