ANTIMENSIA, a kind of Consecrated Table-Cloth, occasionally used in the Greek Church, in lieu of a proper Altar. See ALTAR. F. Goar observes, that in regard the Greeks have but few consecrated Churches; and that consecrated Altars are not things easy to be removed: That Church has for many Ages made use of certain consecrated Stuffs, or Linens called Antimensia, to serve the purposes thereof.
