the texts of the french psalter were brought together from two independent sources: the poet clément marot and the theologian théodore de bèze. marot and beza's psalms appeared in a number of different collections, published between 1533 and 1543; in the latter year marot published "cinquante pseaumes", a collection of 50 psalms rendered into french verse. the full psalter containing all 150 canonical psalms, plus the gospel canticle "cantique de siméon" ("song of simeon"), appeared in 1562.
