The frontal (antipendium, pallium altaris) is an appendage
which covers the entire front of the altar, from the lower part of the
table (mensa) to the predella, and from the gospel corner to that of
the epistle side. Its origin may probably be traced to the curtains or
veils of silk, or of other precious material, which hung over the open
space under the altar, to preserve the shrines of the saints usually
deposited there. Later, these curtains were converted into one piece of
drapery which covered the whole front of the altar and was suspended
from the table of the altar. The use of a frontal which covers only a
small portion of the front of the altar is forbidden (Cong Sac. Rit.,
10 September, 1898). If the altar is so placed that its back can be
seen by the people, that part should likewise be covered with an
antipendium (Caerem. Episc., I, iii, 11). Its material is not
prescribed by the rubrics. It is sometimes made of precious metals,
adorned with enamels and jewels, of wood, painted, gilt, embossed, and
often set with crystals or of cloth of gold, velvet, or silk
embroidered and occasionally enriched with pearls, but it is usually of
the same material as that of the sacred vestments. It is evidently
intended as an ornament of the altar (Rubr. Gen. Miss., tit.). Hence if
the altar is made of wood or marble, and its front is beautifully
painted or decorated, or if the table is supported by columns, and a
reliquary is placed under it, it may be considered sufficiently
ornamented, and the antipendium would not be necessary; nevertheless,
even in such cases, on solemn occasions more precious and elaborate
ones should be used (Caerem. Episc., I, xii, 11). The antipendium may
be ornamented with images, pictures of Christ, representations of some
fact of His life or such as refer to the Eucharistic Mystery, or with
emblems that refer in some manner to the Blessed Sacrament -- a lamb, a
pelican, the chalice and host, etc. Pictures of the saint in whose
honour the altar is dedicated to God, and emblems referring to such
saint, may be used. It is forbidden to ornament the black antipendium
with skulls, cross-bones, etc. (Caerem. Episc., II, xi, 1). The
antipendium may be fastened to little hooks or buttons, which are
attached to-the lower part of the table of the altar or it may be
pinned to one of the lower altar-cloths or attached to a light wooden
frame which fits tightly in the space between the mensa and the
predella. A guard about three inches wide (plinth), made of wood
suitably painted. or of polished metal, may be placed at its lower
extremity, resting on the predella, so as to prevent its being easily
injured by those who move about the altar. Regularly, the colour of the
antipendium should correspond with the colour of the feast or office of
the day (Caerem. Episc., I, xii, 11). The Missal (Rubr. Gen., xx) says
this should be the case quoad fieri potest, by which the Missal does
not imply that one colour may be used ad libitum for another, but that
the more precious antipendia of gold, silver, embroidered silk, etc.,
in colours not strictly liturgical, may be used on solemn occasions,
although they do not correspond in colour with the feast or office of
the day (Van der Stappen vol. III, q. 43, ii). The following are
exceptions to the general rule: (1) When the Blessed Sacrament is
publicly exposed the antipendium must be white, whatever the colour of
the vestments may be. If, however, the Exposition takes place
immediately after Mass, or Vespers, the antipendium of the colour of
the Mass, or Vespers, may be retained if the celebrant does not leave
the sanctuary between the Mass, or Vespers, and the Exposition; but if
on these occasions he vests for the exposition outside the sanctuary,
the antipendium if not white must be exchanged for a white one. (2) In
solemn votive Masses the colour of the antipendium must be that of the
vestments. In private votive Masses (missae lectae) its colour
corresponds to that of the office of the day. In private votive Masses
celebrated solemnly, i.e. with deacon and subdeacon, or in chant
(missae cantatae) it is proper that its colour correspond with that of
the vestments. (3) During a solemn Requiem Mass at an altar in the
tabernacle of which the Blessed Sacrament is kept, the black
antipendium cannot be used (Cong. Sac. Rit., 20 March, 1869), but one
of a violet colour should take its place. The Ephemeides Lit., (XI,
663, 1897), states that this decree was revoked by a subsequent decree
of the same Congregation, 1 December, 1882. It seems strange that the
former decree is retained in the latest edition of the Decrees of the
Cong. Sac. Rit. The latter decree is an answer to the question: Under
these circumstances may the antipendium and the conopoeum (cover of the
tabernacle) be black? The answer seems to pass over the antipendium,
and merely says: "At least the canopy over the tabernacle should be of
a violet colour". The antipendium need not be blessed.[1]
