Editing Blanche of Castile (section)

==Patronage and learning==
Blanche was a patron of the arts and owned a variety of books, both in French and in Latin. Some of these were meant as teaching tools for her son. ''Le Miroir de l'Ame'' was dedicated to Blanche. It instructs queens to practise Christian virtues rigorously in daily life. She oversaw the education of her children, all of whom studied Latin. She also insisted on lessons in Christian morals for all of them. Both Louis and [[Saint Isabelle of France|Isabelle]], her only surviving daughter, were canonized.{{sfn|Nolan|2003|p=181-182, 212}}

The chanson ''Amours ou trop tard me suis pris'', a prayer to the Virgin Mary, is often attributed to Blanche.
