Ciboria

A Ciborium (plural Ciboria) is a covered container used to hold the consecrated small Hosts. It is similar to a chalice but covered and larger, used for small Communion hosts of the faithful. It is made of various precious metals, and the interior is commonly gold or gold-plated. Also synonymous with baldachino as the dome-shaped permanent canopy over a high altar, supported by columns and shaped like an inverted cup. (Etymology: Latin ciborium; from Greek kiborion, cup.)
