‘For me, gold is the sun,’ explains octogenarian Columbian artist Olga de Amaral as she describes the importance and stunning impact of the material in her textiles. Hanging assemblages of gold-covered linen positioned near the door of Chelsea’s Lisson Gallery catch the natural light and resemble ancient carved stones; further in the gallery, this piece adds palladium, another metal that reflects light and adds to the luxurious quality of this labor-intensive artwork. (On view in Chelsea through Dec 18th. Masks and proof of vaccination required.)
