Monstrance in chased silver, 17th-century Tuscan craftsmanship. In the tradition of the Catholic Church the monstrance is used to expose a large consecrated host. It is related to the Eucharist and displays the body of Christ to the congregation during the adoration and Eucharist benediction. It is linked to the feast of Corpus Domini, established in the 14th century. Initially, monstrances were similar in shape to reliquaries; but with the Council of Trent in the 16th century, they assumed an independent form, characterized by a large display case with a circular sunburst. This monstrance has a haft shaped like an angel, which supports a transparent casket adorned with rays and adorned with diamonds and rubies which symbolize the blood and water that came out of Christ's side on the cross.
