Oval glass-fronted brass pendant reliquary theca housing first-class ex ossibus (of the bone) relic of Saint Vincent Ferrer. The relic is affixed to a gilt paper starburst surrounded by silver wire ornamentation, and identified in Latin on a fancy manuscript cedula label as Ex Oss. S. Vincentii Fer: (of the bone of Saint Vincent Ferrer). On the back, the theca is secured with a perfectly preserved seal of red Spanish wax bearing an imprint of a coat of an unidentified Roman Catholic Bishop.
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.
