Ghanaian sculptor Brahim El Anatsui's father was a master weaver who taught the tradition of strip-weaving Kente cloths to his sons. This textile technique has become a staple of El Anatsui's art: he amasses and refashions the debris from his community to create majestic, visual narratives that address his personal history and global issues like environmental sustainability. The North American premiere of his four-decade career retrospective When I Last Wrote to You About Africa is at the Royal Ontario Museum in Toronto, having been extended to Feb. 27.
