Reliquary theca with relics of St. Henry the Exuberant (Henry II) & Blessed Osanna of Mantua

Oval glass-fronted brass reliquary theca housing first-class ex ossibus (of the bone) relics of ​Saint Henry the Exuberant and Blessed Osanna of Mantua. The relics are affixed to a red silk ground surrounded by silver wire and gilt paperolle ornamentation and identified in Latin on a manuscript cedulae labels as S. Exuberanti // B. Ossanae V, (Saint [Henry, the] Exuberant // Blessed Ossana, Virgin). On the back, under the protective cap, the theca is secured with a seal of red Spanish wax bearing an imprint of a coat of arms of Fr. Antonio Cantoni (†1781), Bishop of Faenza, Italy (1742–1767) and Archbishop of Ravenna, Italy (1767–1781).

Saint Henry the Exuberant (also known as Saint Henry II, Holy Roman Emperor)(†1024) was born in Bavaria and crowned Holy Roman Emperor by Pope Benedict VIII in 1014. A devout ruler and Benedictine oblate, he promoted Church reforms, supported monasteries, defended the faith in wars, and governed justly despite political challenges. He was canonized in 1146 by Pope Eugene III, and he is the only medieval German emperor to be declared a saint, patron of rulers and the childless.

Blessed Osanna of Mantua (†1505) was an Italian Dominican tertiary, mystic, and virgin. From age five or six, she experienced visions of angels and the Child Jesus crowned with thorns, inspiring her lifelong consecration to God. At fourteen, defying an arranged marriage, she secretly received the Dominican tertiary habit. A stigmatic with invisible wounds, she lived ascetically, blended contemplation with charity, advised the Gonzaga rulers, and offered spiritual counsel. She was canonized in 1694 by Pope Innocent XII and her Feast day is commemorated on June 18.
