1911 Encyclopædia Britannica/Griselda
Griselda, a heroine of romance. She is said to have been the wife of Walter, marquis of Saluces or Saluzzo, in the 11th century, and her misfortunes were considered to belong to history when they were handled by Boccaccio and Petrarch, although the probability is that Boccaccio borrowed his narrative from a Provencal fabliau. He included it in the recitations of the tenth day (Decamerone), and must have written it about 1350. Petrarch related it in a Latin letter in 1373, and his translation formed the basis of much of the later literature. The letter was printed by Ulrich Zel about 1470, and often subsequently. It was translated into French as La Patience de Griselidis and printed at Bréhan-Loudéac in 1484, and its popularity is shown by the number of early editions quoted by Brunet (Manuel du libraire, s.v. Petrarca). The story was dramatized in 1395, and a Mystère de Griselidis, marquise de Saluses par personnaiges was printed by Jehan Bonfons (no date). Chaucer followed Petrarch's version in the Canterbury Tales. Ralph Radcliffe, who flourished under Henry VIII., is said to have written a play on the subject, and the story was dramatized by Thomas Dekker, Henry Chettle and W. Haughton in 1603.
