Traité des vapeurs : où leur origine, leurs effets, et leurs remedes sont mécaniquement expliquez
A 1689 French medical treatise on vapours, published in Paris by the widow of Denis Nion and aimed at physicians and readers interested in hypochondria and bodily humours. Its pictures are small woodcut typographic ornaments: a crowned French shield with fleurs-de-lis under a sunburst, flanked by scrolling foliage, serpents and scorpions, plus a fleur-de-lis-like acanthus head and a square corner-piece of curling leaves. A designer could take from them the dense, symmetrical, mirrored ornament typical of seventeenth-century French printing, useful for borders, headers and vignettes.
