Traité des eaux de Spa, avec une analyse d'icelles, leurs vertus et usage
A 1699 French medical treatise by Edmond Nessel on the mineral waters of Spa, published in Spa and Liège for readers interested in its analysis and uses. The single picture is a small woodcut of an ornate covered urn on a pedestal, with a plain block base and scrolled handles, the kind of tailpiece or vignette a designer could adapt for ornamental borders and classical motifs.
