Enguerrand was a nobleman who excelled in "courtly" behavior and a loyal vassal of the French king Charles V of France.
These were the twelve flowers of authority, faith, virtue, temperance, piety, prudence, sincerity, honor, power, mercy, generosity, solidarity and largesse.
How the order looked is unknown; at this time it was usual that a common recognition sign was worn hanging from a chain around the neck or was embroidered on the clothes.
On 26 April 1390, as he prepared for a campaign against the Muslims in the kingdom of Barbary Coast, gave Enguerrand the Order of the Celestines, a strict and ascetic monastic order, an income of 400 livres per year and money to found a cloister for twenty monks on his property in Villeneuve-Saint-Germain on the banks of the Aisne, just outside Soissons.
The document speaks of "perpetual prayers for himself, his current wife, his ancestors and descendants and all the knights and ladies of his Order of the Crown".
