Reliquary theca with relic of St. Luxorius (Lussorio or Rossore), Martyr of Sardinia

Oval glass-fronted silver pendant reliquary theca housing the first-class ex ossibus (of the bone) relic of Saint Luxurius of Sardinia.  A substantial relic is affixed to a gilt-paper starburst on a ground of salmon-colored silk, surrounded by silver wire ornamentation, and identified in Latin on a fancy manuscript cedula label as Ex Oss. S. Luxurius, Martyr[is]  (of the bone of  Saint Luxurius, Martyr). On the back, the theca is secured with a seal of red Spanish wax bearing an imprint of a coat of arms of Fr. Francesco Maria Ginori (†1775), Bishop of Fiesole, Italy (1736–1775).

Saint Luxurius or Luxorius († 304)(Italian - Lussorio; Pisan dialect - Rossore) was a Roman official in Sardinia venerated as a martyr saint by the Roman Catholic Church. Apparitor to Delphius, the praeses or governor of the island, he was converted to Christianity by reading the Psalms. He was beheaded during the fourth of Diocletian's persecutions for refusing to sacrifice to idols in the city of Forum Traiani. He is the patron saint of several Italian cities, the largest of which is Pisa (where he is honored under the name of "Rossore". In Borore, a small town in central Sardinia, San Lussorio Martire is the patron saint. The saint is celebrated twice a year: in April, with an almost exclusively religious ceremony, and in August, with important religious celebrations that last three days (20-21-22), followed by novenas in the rural sanctuary dedicated to the saint.
