It became the home of King Stanisław Leszczyński, last duke of LorraineandBar.
During the medieval period the property, consisting of more than 4 km2 (990 acres), was part of a group of 32 villages near-by that created the then known as “L'Anjou”.

The Golden Canon of page design was officially named by John Tschichold in 1953. As pictured in the GIF above, it involved the matching of diagonals to create a text area that held a 2:3 ratio, and that was oriented to the upper inner corner of the page. This spread of the Valerius maximus provides a real-life example of the Golden Canon, which appeared to be ubiquitous despite the inconsistencies between measuring systems in the medieval world.
