Reliquary theca housing ex ossibus (of the bone) relic of Saint Vincent Ferrer. The relic is affixed to a pale blue background and identified on a manuscript cedula label as S. Vin. Fer. On the back, under a protective cap, the theca is secured by a perfectly preserved seal of red Spanish wax bearing an imprint of a coat of arms of Pope Pius VI (p. 1775-1799), indicating that the relic was a direct papal gift from the Vatican.
Saint Vincent Ferrer, O.P., (†1419) was a Valencian Dominican friar, who gained acclaim as a missionary and a logician who was canonized by Pope Calixtus III in 1455. His feast day is celebrated on 5 April. He is a holy patron of builders, construction workers, plumbers, fishermen, and orphanages.
