When Marshall Kath, a private collector in Dallas, took note of a 2009 Sotheby’s Fine European Furniture and Antiques auction in New York City, he was looking for a piece that would spark conversation. Mr. Kath eventually purchased an attention commanding, 10 ft by 9.5 ft historic 17th-century tapestry that does just that. Titled A Brussels Old Testament Tapestry Depicting the Joseph Interpreting the Pharaoh’s Dreams, From a Series of The Story of Joseph, the tapestry was commissioned by either a royal family as a way of depicting a peaceful, serene life, or a church as a visual representation of significant elements of a particular faith; in this case, Jewish or Christian.
