This checklist is part of a series of volumes describing the silver-stained glass roundels and unipartite panels from the 15th to the 18th centuries to be found in public buildings, museums and private collections in the present five provinces of Flanders (Belgium), as well as documented roundels and unipartite panels whose whereabouts are presently unknown or which have been moved to other locations or collections in the past. The checklist also mentions all known related material, and where possible, photographs of this material have been added. As far as the related material is concerned, the relevant publications are also mentioned. The related material includes direct designs, like drawings or engravings, and drawings and roundels which belong to either the same series or which are copies of these series. This volume covers the Provinces of West Flanders and East Flanders. The publication of the checklists for the provinces Limburg and Flemish Brabant (Vol.3) is planned for the near future. An inventory of the roundels in The Netherlands is also foreseen.
