On December 10-11, and on December 16-18, a local Cambridge-based nonprofit will host two craft festivals highlighting Indigenous art from around the world. Among them, artists from various regions of Peru will participate. Their art will showcase the rich diversity of Peruvian Indigenous cultures, with crafts ranging from hand-carved wooden scenes called retablos, to silver jewelry inspired by pre-Columbian textiles, to music featuring Andean winds and strings.
