Just for fun--sacrarium and piscina
sacrarium (plural sacraria)
- (in Ancient Rome) A place where sacred objects were kept, either in a temple (the adytum) or in a house (holding the penates)
- The area surrounding the altar of a Christian church; the sanctuary or piscina. Sometimes specifically a drain directly to the earth, perhaps including reference to a basin, for washing vessels from consecration.
A piscina is a shallow basin placed near the altar of a church, or else in the vestry or sacristy, used for washing the communion vessels. The sacrarium is the drain itself. Anglicans usually refer to the basin, calling it a piscina. Roman Catholics usually refer to the drain, and by extension, the basin, as the sacrarium. They are often made of stone and fitted with a drain, and are in some cases used to dispose of materials used in the sacraments and water from liturgical ablutions. They are found in Roman Catholic, Anglican, and Lutheranchurches, and a similar vessel is used in Eastern Orthodox churches.
