KABUL, Afghanistan — Inside an art exhibit called Abarzanan — Superwomen — stones the size of pomegranates hover above a mannequin wearing a dress fashioned from a white burial shroud.

The display commemorates a young Afghan woman, Rukhshana, 19, who was stoned to death by village men in 2015. She had fled an arranged marriage to a much older man and eloped with a young lover in a Taliban-controlled district in western Afghanistan.

The Superwomen exhibit, created by the photographer and artist Rada Akbar, honors eight trailblazing women in Afghanistan and the region — among them an ancient queen and a 10th-century poet — at a fearful time for Afghan women.

After 19 years of halting gains after the collapse of Taliban rule, a Feb. 29 agreement between the United States and the insurgents has filled many Afghan women with dread. The agreement does not mention women’s rights but does envision a return of the Taliban to a future Afghan government after American troops withdraw.
