In 1951, under the shadow of the Great Pyramid of Giza, Egyptian art professor Ramses Wissa Wassef founded an art center and school that embraced ancient practices of tapestry making. The center flourished, and many of its tapestries are now considered Egyptian national treasures. Engineer and entrepreneur David Williams was captivated by these works, and has become an expert and collector. This week, he presents a lecture titled ‘Tapestries of Egypt: An Experiment in Creativity,’ and is joined by artist and conservator Joyce Ertel Hulbert in discussing the tapestry medium as a vehicle for creative expression. Wednesday, March 11, at Calabi Gallery, 456 10th St., Santa Rosa. 7pm. 707.781.7070.
