Gift of Mr. and Mrs. James M. Osborn for the Linton Collection of African Art
The a-Rong-a-Thoma mask represents a fantastical male water creature that resembles a hippopotamus, with ram horns, huge conical nostrils, and a large open jaw baring teeth. The raffia costume consists of a short, thick fringe (still attached here), a long cape, a skirt, and pom-poms on the feet, all dyed a dull red. Several A-Rong-a-Thoma may appear during an evening performance following the coronation of a chief, at the funeral of a chief, at a sacrifice to the community's ancestors, or at a welcoming celebration honoring important visitors.  
This object is on view at the gallery.
