Round glass-fronted yellow-metal reliquary theca housing the first-class Ex ossibus (of the bone) relic of the Blessed Domingo Iturrate Zubero. The relic is affixed to a red silk ground and identified in Latin on a typeset cedula label as B. Dominicus Iturrate osst (Blessed Domingo Iturrate O.SS.T.). On the back, under a protective cap, the theca is secured with a seal of red Spanish wax bearing an imprint of a coat of arms of the Trinitarian Order. The relic is accompanied by the original matching authentics document issued and sealed on 30 October 1983 (on the very day of his beatification) by the Postulator General of the Order responsible for the Causes of Canonization.
Blessed Domingo Iturrate Zubero O.SS.T. (†1927), also known by his religious name Domingo of the Blessed Sacrament, was a Spanish Roman Catholic priest and a professed member of the Trinitarian Order. Zubero grappled with tuberculosis as he underwent his studies in Rome, where he was ordained to the priesthood, and he became noted for his staunch devotion to the Mother of God. He was beatified by Pope John Paul II on 30 October 1983. His feast is celebrated on 11 May.
