The exact dates of his birth and death are unknown, and not much detail has surfaced concerning his career. Conjectures place him first in the house of the
Dominicans at
Paris between 1215 and 1220, and later at the Dominican monastery founded by
Louis IX of France at
Beauvais in
Picardy. It is more certain, however, that he held the post of "reader" at the monastery of
Royaumont on the
Oise, not far from Paris, also founded by Louis IX, between 1228 and 1235. Around the late 1230s, Vincent had begun working on the
Great Mirror and in 1244 he had completed the first draft. The king read the books that Vincent compiled and supplied the funds for procuring copies of such authors as he required. Queen
Margaret of Provence and her son-in-law,
Theobald V of Champagne and Navarre, are also named among those who urged him to the composition of his "little works", especially
De morali principis institutione. In the late 1240s, Vincent was working on his
Opus which included
On the Education of Noble Girls (
De Eruditione Filiorum Nobilium). In this work he styles himself as "Vincentius Belvacensis, de ordine praedicatorum, qualiscumque lector in monasterio de Regali Monte". Though Vincent may have been summoned to Royaumont before 1240, there is no evidence that he lived there before the return of Louis IX and his wife from the
Holy Land. It is possible that he left Royaumont in 1260, which is also the approximate year that he wrote
Tractatus Consolatorius, which was occasioned by the death of the king's son Louis that year. Between the years 1260 and 1264 Vincent sent the first completed book of the
Opus to Louis IX and Thibaut V. In 1264 he died. ==
