Monstrance

A monstrance, also known as an ostensorium, is a vessel used in Roman Catholic, Old Catholic, High Church Lutheran and Anglican churches for the display on an altar of some object of piety, such as the consecrated Eucharistic host during Eucharistic adoration or Benediction of the Blessed Sacrament.

The sun design derives from Latin American Catholicism, where missionaries employed monstrances with the sunburst to appropriate sun imagery to the eucharist, and hence supplant sun worship among the natives.

Here are some beautiful examples:
