Of a very different quality was the Étienne Boileau, selected by Saint-Louis to fill this important post, and who, according to Joinville, "executed such good and straight justice," that "no malefactor, thief, or murderer dared to remain in Paris but he was immediately hanged and exterminated; neither family nor gold nor silver could save him." The king was so well satisfied with his _prévôt_ that he caused him to be seated by his side when he presided at the Châtelet, and, in order to preserve to this office, after Boileau, the lustre which he had conferred upon it, he separated from it the receipt of the funds of the royal domains, and created for the latter a receiver, a guardian of the seals, and sixty notaries who exercised their functions under the authority of the _prévôt_, who, subsequently, was entitled _garde de la prévôt de Paris_. The _guet royal_ was established, and the _prévôt_ drew up the ancient regulations of the hundred trades or handicrafts which existed in the capital, "in order to establish peace and order in industry as he had established it in the nation." These trades were divided into various great corporations. Under this wise king, also, the Hanse, or confraternity, of the _marchandise de l'eau_ became definitely the _municipalité parisienne_; for about a century the members of this confraternity had been called _échevins jures_, and their chief was known as the _prévôt des marchands de l'eau_, or _prévôt de confrérie de l'eau_. The numerous privileges which this corporation enjoyed passed in course of time to the _prévôt des marchands_, who acquired, successively, the administration of the _rentes_ or funds drawn from the Hôtel de Ville, the regulation of public ceremonies, the care and construction of the public monuments, the opening of new streets, etc. The ancient privileges of the Hanse had previously been confirmed at various times, amongst others, by Louis VII.
