The Stavelot Triptych is a medieval reliquary and portable altar in gold and enamel intended to protect, honor and display pieces of the True Cross.[1][2] Created by Mosan artists—"Mosan" signifies the valley of the Meuse river—around 1156[1] at Stavelot Abbey in present-day Belgium.[1][2] The work is a masterpiece of Romanesque goldsmith's work and is today in the Morgan Library & Museum in New York City.[1][2]
