Vase to hold flowers for the decoration of the altar. The Cæremoniale Episcoporum (I, xii, n. 12) says that between the candlesticks on the altar may be placed natural or artificial flowers, which are certainly appropriate ornaments of the altar. The flowers referred to are cut flowers, leaves, and ferns, rather than plants imbedded in soil in large flowerpots, although the latter may fitly be used for the decoration of the sanctuary around the altar. If artificial flowers are used they ought to be made of superior material, as the word serico (ibid.) evidently implies, and represent with some acouracy the natural variations. Flowers of paper, cheap muslin, or calico, and other inferior materials, and such as are old and soiled, should never be allowed on the altar.
