 This impression was confirmed by an analysis of the prominent designs at the center of the screen faces, which have now been identified as religious symbols.The rosette represented the Phrygian goddess Matar and the curved legs her two attendant lions, in an abstract version of the figures in the niche of Arslan Kaya, the monumental rock-cut shrine of the Phrygian highlands.The Tumulus MM screens thus took the form of portable shrines of the goddess Matar.
