This work includes two volumes in 8° the first one finished on 1 November 1560 and the second one on 4 July 1561. The great rarity of this book is explained by the small number of copies that were printed; in fact this Breviary was used exclusively for the canons of Saint Paul. The only known copy is in the Bibliothèque Ulysse Capitaine [fr]; it is currently on display at the Curtius Museum
