Title: Louis IX of France
Content:  Much of what is known of Louis's life comes from Jean de Joinville's famous Life of Saint Louis. Joinville was a close friend, confidant, and counselor to the king. He participated as a witness in the papal inquest into Louis's life that resulted in his canonisation in 1297 by Pope Boniface VIII. Two other important biographies were written by the king's confessor, Geoffrey of Beaulieu, and his chaplain, William of Chartres. While several individuals wrote biographies in the decades following the king's death, only Jean of Joinville, Geoffrey of Beaulieu, and William of Chartres wrote from personal knowledge of the king and of the events they describe, and all three are biased favorably to the king. The fourth important source of information is William of Saint-Parthus's 19th-century biography, which he wrote using material from the papal inquest mentioned above.

Title: Louis of Toulouse
Content:  this ambivalently dynastic and ecclesiastical position, in a territory between Provence and Aquitaine that was essential to Angevin interests, despite the princely standing that had won him this important appointment at the age of about 22, Louis rapidly gained a reputation for serving the poor, feeding the hungry, and ignoring his own needs. After just six months, however, apparently exhausted by his labors, he abandoned the position of Bishop. Shortly thereafter he died at Brignoles of a fever, possibly typhoid, at age 23. Two music theory treatises, De musicae commendacione and Sentencia in musica sonora subiecti, are sometimes attributed to him, but are now thought to be the work of Lodewijk Heyligen (1304–1361).

Very devout, he was a fervent supporter of the Jesuits, like his mother and sisters, and was led by them to have a devotion to the Sacred Heart.
