The rite of ''Dedication of a church and of the altar'' points out that the celebration of the Eucharist is "the principal and the most ancient part of the whole rite, because the celebration of the eucharist is in the closest harmony with the rite of the dedication of a church", and "the eucharist, which sanctifies the hearts of those who receive it, in a sense consecrates the altar and the place of celebration, as the ancient Fathers of the Church often assert: 'This altar should be an object of awe: by nature it is stone, but it is made holy when it receives the body of Christ.

. In the East, early churches had the altar at the east end and the priest, facing east, stood at the western side of the altar, with his back to the people and the doors. This later became the common practice also in western Europe. It was adopted in Rome only in the 8th or 9th century. The churches that Christians built after the legalization of their religion in the Roman Empire were not modelled on pagan temples, which were not intended to accommodate large numbers of people. The model used was that of the public basilicas that served for meetings such as sessions of law courts. These were generally spacious, and the interior was divided by two or four rows of pillars, forming a central

The earliest altars for celebrating the Christian Eucharist were of wood and identical in form with ordinary house tables, as was doubtless used at the Last Supper. The only such ancient wooden table still preserved is in the

(c. 335 – c. 395) speaks of the consecration of an altar made of stone (''De Christi Baptismate''). Since wood is subject to decay, the baser metals to corrosion, and the more precious metals were too expensive, stone became in course of time the ordinary material for an altar. The earliest decree of a council prescribing that an altar which is to be consecrated should be of stone is that of the provincial council of Epeaune (

distinguishes between the "table" of an altar (the top) and the supports or base. The latter, provided it is dignified and solid, may be of any material. On the other hand, "in keeping with the Church’s traditional practice and with what the altar signifies, the table of a fixed altar should be of stone and indeed of natural stone", except where the episcopal conference authorizes the use of another material (such as wood) that is dignified, solid and well-crafted. "A movable altar may be constructed of any noble and solid material suited to liturgical use, according to the traditions and usages of the different regions." In

walls so as to form an arch-like niche. Both in the catacombs and in the above-ground churches the altar could also be a square or oblong block of stone resting on one or more columns (up to six) or on a masonry structure that enclosed the relics of martyrs. Instead of masonry, upright stone slabs could be used, thus forming, with the top slab, a stone chest containing the relics. This no doubt brought about both a change of form, from that of a simple table to that of a chest or tomb.

liturgy, before the reforms of the second half of the twentieth century, had complex rules about a distinction between a "fixed altar" and a "portable altar".

or any altar table consecrated separately from its supports. Usually an altar should be fixed and ritually dedicated, but a mere blessing is sufficient for a movable altar. In a church a fixed altar is appropriate, but in other places set aside for sacred celebrations the altar may be movable.


Relics

The practice of celebrating the Eucharist over the graves of martyrs is probably the origin of the rule that demanded that every altar must contain the relics of martyrs. The General Instruction of the Roman Missal states that "the practice of the deposition of relics of Saints, even those not Martyrs, under the altar to be dedicated is fittingly retained. Care should be taken, however, to ensure the authenticity of such relics." The ''
Caeremoniale Episcoporum The ''Cæremoniale Episcoporum'' (Ceremonial of Bishops) is a book that describes the church services to be performed by bishops of the Latin Church of the Catholic Church. History Pope Clement VIII published on 14 July 1600 the first book to be ...
'' adds: "Such relics should be of a size sufficient for them to be recognized as parts of human bodies; hence excessively small relics of one or more saints must not be placed beneath the altar. The greatest care must be taken to determine whether the relics in question are authentic; it is better for an altar to be dedicated without relics than to have relics of doubtful authenticity placed beneath it. A reliquary must not be placed upon the altar or set into the table of the altar; it must be placed beneath the table of the altar, as the design of the altar permits." In earlier centuries minute portions of relics were inserted into the table of the altar and also into the

s that at that time were called movable altars. The cavity into which they were placed was called the ''sepulchrum'' (

for 'tomb'). The relics could be of several saints, but two had to be martyrs until 1906, when the Congregation of Rites decided that it was sufficient to enclose relics of two canonized saints of whom one was a martyr. The relics were placed in a reliquary of lead, silver, or gold, large enough to contain also three grains of incense and a small attestation of consecration on a piece of parchment. In an altar stone, the relics were inserted directly, without a reliquary. There were precise rules also about where exactly in the altar the relics were to be placed and about the stone cover for the cavity. In ancient churches in which the altar is built over the tomb of a saint or over the relics that have been placed there, a niche below the altar offered a view of the tomb or reliquary and allowed the faithful to touch it and to place in contact with it that would then be venerated as second-class relics. The best known example is the Niche of the Palliums in St. Peter's Basilica in the Vatican. It is now approached by descending steps, since the present floor is considerably higher than that of the original basilica. Other churches also have in front of the altar a similar semicircular hollow area, known as the ''confessio'', even if the altar is not built over a holy tomb, as in the

). Even within an elevated sanctuary, the altar itself is often placed on a higher platform set off by one or more steps. The platform is known as the predella. The altar may also be marked with a surmounting ciborium, sometimes called a baldachin. As well as the altar, the sanctuary contains the credence table, the ambo and the seats for the clergy.


Steps

Later, the number of steps was increased. It became the norm that the main altar of a church should be raised above the level of the sanctuary by three steps, while side altars had a single step. The papal altar in St Peter's Basilica in the Vatican is approached by seven steps. An odd number was always chosen. Since it was considered proper to use the right foot in taking a first step, this ensured that the priest, having ascended the first of the steps with his right foot would also enter the predella (the platform or footpace on which the altar stood) with his right foot. The same rule applied to pre-Christian temples, as indicated by

This practice declined as the introduction of other structures that screened the altar, such as the

In early times, before the break-up of the Roman Empire exposed such objects to sacking and looting, the consecrated bread of the Eucharist (the reserved sacrament) was kept in a gold or silver dove, sometimes enclosed in a silver tower, suspended by fine chains from the ciborium that sheltered the altar. Instead of a four-column ciborium a movable canopy (called a tester) was in some churches suspended from the ceiling above the altar or a fixed canopy attached to the wall was employed.Augustin Joseph Schulte, "Altar Canopy" in ''The Catholic Encyclopedia'' (1907)

should be placed at the foot of the cross. It stated also that "nothing whatever unrelated to the sacrifice of the Mass and the adornment of the altar itself is to be placed on it". Although the Roman Missal thus spoke of the cross and the candlesticks as the altar, it became customary to add to the edge of altars one or more steps, slightly higher than the altar itself, on which to place the crucifix, candlesticks, flowers, reliquaries, and other ornaments. These adjuncts became common when, in the sixteenth century, church tabernacles were added to altars, requiring that most of the altars concerned be provided with these superstructures, which are known as altar ledges, degrees, gradini or superstructural steps. The front of these steps was sometimes painted and decorated. Thus the gradini of

This base is called the predella (not to be confused with the same term when used of the platform on which the altar sits), and may illustrate episodes in the life of the saint whom the altar celebrates. Some altarpieces are known as

s. In these the fixed central panel is flanked by two or more hinged panels, which can be moved to hide the central painting and the paintings on the side-panels themselves, leaving visible only the reverse of the side-panels, which are usually relatively plain. They can then be opened to display the images on feastdays. According to the number of panels, these are called triptychs (if of three panels) or polyptychs (if the panels are more than three).

, the altar should be covered by at least one white altar cloth: "Out of reverence for the celebration of the memorial of the Lord and for the banquet in which the Body and Blood of the Lord are offered, there should be, on an altar where this is celebrated, there should be at least one white cloth, its shape, size, and decoration in keeping with the altar’s design." The pre-1969 regulations prescribed white altar cloths, the topmost being long enough to reach the ground at both ends. 19th and early 20th-century regulations required that the cloths be of linen or hemp and not of any other material, even if of equivalent or higher quality.Augustin Joseph Schulte, "Altar Cloths" in ''The Catholic Encyclopedia'' (New York 1907)
/ref> In addition, it was customary to place directly on the altar, beneath the three obligatory altar cloths, a cloth waxed on one side that was called the chrismale or cere cloth and that served to keep the altar cloths dry. When the altar is not used for a liturgical service, the altar cloths may be protected against being stained or soiled by placing over them an altar protector or altar cover made of cloth, baize or velvet large enough to hang down a little on all sides. This is known as the vesperale or stragulum. When in the period immediately preceding the late twentieth century altars were generally built attached to or close to a wall, it became customary to cover with drapery the front of the altar, the only part visible to the congregation. This drapery was called the
antependium An ''antependium'' (from Latin ''ante-'' and ''pendēre'' "to hang before"; pl: ''antependia''), also known as a ''parament'' or ''hanging'', or, when speaking specifically of the hanging for the altar, an altar frontal (Latin: ''pallium altari ...
or altar frontal, terms often applied also to sculptural or other ornamentation of the altar front itself. It covered the whole front of the altar, partial coverings being forbidden. It was obligatory unless the altar front was particularly artistic, and even in such cases it should be used on more solemn occasions. Its origin was thought to have derived from the curtains or veils of silk or other precious material hanging over the open space under the altar table to preserve the shrine of saints deposited there. In the Middle Ages a similar function was performed by an "altar stole", an ornament in the shape of the ends of a stole attached to the front of the altar. In the 21st century the altar in a Catholic church is generally left visible.


Candles and candlesticks

According to the '' General Instruction of the Roman Missal'' (1969): "On or next to the altar are to be placed candlesticks with lighted
candles A candle is an ignitable wick embedded in wax, or another flammable solid substance such as tallow, that provides light, and in some cases, a fragrance. A candle can also provide heat or a method of keeping time. A person who makes candl ...
: at least two in any celebration, or even four or six, especially for a Sunday Mass or a holy day of obligation. If the Diocesan Bishop celebrates, then seven candlesticks with lighted candles should be used. The candles ��may also be carried in the procession at the Entrance." While only two lighted candles are now obligatory and may be placed beside the altar rather than on it, the pre-1969 rubrics (which did not envisage the candles being brought in the Entrance procession) required that they be on the altar itself (in practice, however, they were often placed on the altar shelf instead) and should be four at a Low Mass celebrated by a bishop, four or six at a Missa cantata, six at a Solemn Mass and seven at a Pontifical High Mass. In the last case, the seventh candle was not lit if the bishop was celebrating outside his own diocese. There were also rules, developed over centuries, about the material from which the candlesticks were to be made and about the relative heights of the candles. Candles appear not to have been placed on the altar before the twelfth century, but earlier writings speak of

. Liturgical books of the same pre-1969 period speak of the placing of flowers (even good-quality artificial ones) in vases between the candlesticks on the altar.Augustin Joseph Schulte, "Altar Vase" in ''The Catholic Encyclopedia'' (New York 1907)
/ref> The present rule is: "During Advent the floral decoration of the altar should be marked by a moderation suited to the character of this time of year, without expressing prematurely the full joy of the Nativity of the Lord. During Lent it is forbidden for the altar to be decorated with flowers.
Laetare Sunday Laetare Sunday (Church Latin: ; Classical Latin: ; English: , , , , ) is the fourth Sunday in the season of Lent, in the Western Christian liturgical calendar. Traditionally, this Sunday has been a day of celebration, within the austere period ...
(Fourth Sunday of Lent), solemnities, and feasts are exceptions. Floral decoration should always show moderation and placed around the altar rather than on its mensa. Only what is required for the celebration of the Mass may be placed on the mensa of the altar: namely, from the beginning of the celebration until the proclamation of the Gospel, the Book of the Gospels; then from the Presentation of the Gifts until the purification of the vessels, the chalice with the paten, a ciborium, if necessary, and, finally, the corporal, the purificator, the pall, and the Missal." The candlesticks consist of five principal parts: the foot, the stem, the knob, the bowl to catch drippings, and the pricket on which the candle is placed. Altar candlesticks may be made of any material suitable for candlesticks, with the exception that silvered candlesticks may not be used on Good Friday. They may never be used for funeral celebrations.


Tabernacle sometimes placed on an altar

Tabernacle According to the Hebrew Bible, the tabernacle ( he, מִשְׁכַּן, mīškān, residence, dwelling place), also known as the Tent of the Congregation ( he, link=no, אֹהֶל מוֹעֵד, ’ōhel mō‘ēḏ, also Tent of Meeting, etc.), ...

did not envisage placing the tabernacle on an altar: it laid down instead that the altar card containing some of the principal prayers of the Mass should rest against a cross placed midway on the altar (''Rubricae generales Missalis'', XX - ''De Praeparatione Altaris, et Ornamentorum eius''). However, in 1614 Pope Paul V ordered the churches of his diocese of Rome to put the tabernacle on some altars. Whether on the main altar of the church or in a special chapel, the tabernacle became more and more large and ornate, to the extent of dominating the altar. The present rules are as follows:
