The second edition appeared in Lyons in 1715 under the title L"Eloquence chrétienne dans l"idée et dans la pratique. The work, which comprises twenty-three chapters, does not follow the rigorous order of a didactical treatise and is without the dryness of a scholastic manual.
lieutenant has been called "un livre éloquent sur l"éloquence" (An eloquent book on Eloquence).
lieutenant contains a series of talks on the faults to be avoided in the matter and form of sermons, on oratorical action and decorum. One of them, Jacques L"enfant (1661–1728), carefully annotated it, and another, Kornrumpff, translated it into German.
An Italian translation also appeared during Gisbert"s lifetime, and later a Latin translation. As a sort of supplement, Gisbert wrote reflections on the collections of sermons printed in France from 1570 to about 1670.
In this he considers ten orators before Jacques-Bénigne Bossuet and Louis Bourdaloue.
The manuscript of this Historie critique de la chaire française depuis François Ier was lost but was finally recovered by Manager Puyol and published by Fathers Chérot and Griselle, Society of Jesus (Jesuit), in the Revue Bourdaloue, 1902-1904. Gisbert died, aged 74, in Montpellier.
