Boncompagno da Signa (also Boncompagnus or Boncompagni; c. 1165/1175 – after 1240) was an Italian scholar, grammarian, historian, and philosopher.
In the early thirteenth century, he was one of the first Western European authors to write in the vernacular, in his case Italian.
His love of elaborate practical jokes is described by Helen Waddell in The Wandering Scholars (1927).
This book especially made widely known the self-sacrifice of the widow Stamira, who had a major role in saving the city.
Of this book, three copies remain: one is kept in the Vatican, the second in the National Library of Paris and the third remained unpublished until 1723, when it was bought by Father Auriberti of Brescia, from which the text was translated and published by the historian Ludovico Antonio Muratori in 1725.
