The work edited is a volume printed c. 1675-1680 with incipit: Psalterium dispositum per annum, It represents a private initiative by Jean-Baptiste Colbert, the finance minister of Louis XIV, for use in his household. Compiled chiefly by the abbe Jean Gallois (1632-1707), it has affinities with the breviary of Cardinal Quinonez in some of its principles, though it is by no means a copy of Quinonez's work. It also owed much to the Paris Breviary of 1680, to the preparatory material of which Colbert's position presumably gave him access.
