Old collections, real or fake, are a basic part of the collection history of an antiquity or artwork. This article is a starting point for a study of the concept: how old collections are employed, what functions they have, and how fictitious old collections are chosen and constructed. To explore these concepts, the article considers the example of Cumberland Clark, an early 20th-century collector who serves as the putative origin of cuneiform tablets in a handful of present-day collections, most notably the Schøyen Collection. This article looks at the life and collections of Cumberland Clark, then argues that the Clark provenance for current collections is a fabrication, and concludes by looking at Clark in the context of other old collections in order to draw some lessons about fabricated provenance.
