Vincent of Beauvais
Vincent was preparing a four-volume work on the training and competences a Christian monarch should have. He only succeeded in completing two parts of it.
This page offers a brief description of the De morali principis institutione and a list of manuscripts and editions. As Vincent demonstrates in this work, power, wisdom and goodness are the key competences of a Christian monarch.
The De eruditione filiorum nobilium focuses on the education of noble children. This page briefly describes the work and its manuscripts and editions.
