Traité du ris, contenant son essance, ses causes, et mervelheus essais [microforme]
Laurent Joubert's 1579 treatise on laughter, printed in Paris by N. Chesneau, is a learned medical and philosophical work written for a French readership of the late sixteenth century. The one picture is a black decorative headpiece above a line of capitals, with interlaced foliage, scrolls and small animal forms in dense woodcut-style blackwork that a designer could borrow for ornamental borders and early modern dividers.
