Embracing her Irish roots Meghan Walsh presents “Athbheochan: Untranslatable Wisdom;” an Irish Gaelic work that means “revival.” Each of the pieces in the series contain hidden, untranslatable words from all over the world embedded in a flowing and undulating series of three-dimensional relief mosaics of stone glass and other materials including tire scrap and a horseshoe crab carcass. Athbheachan runs through March 2, in Blank Space inside the Anacostia Arts Center. The Anacostia Arts Center is at 1231 Good Hope Rd. SE. anacostiaartscenter.com.
