Over the transom, three citations making it perfectly clear that NOTHING is EVER to be placed upon the Altar of the Holy Sacrifice, even in the Novus Ordo.  This is why Antipope Bergoglio SPECIFICALLY ordered the emcee, Msgr. Guido Marini, to put the Pachamama dragon demon plant ON the Altar.  SHAME ON GUIDO MARINI FOR DOING IT, KNOWING FULL WELL AS HE DOES THAT IT WAS WILDLY ILLICIT AND SCANDALOUS.

“During the offertory or immediately before it, a collection of money or other gifts for the poor or for the church is taken up. In the Roman Rite Mass, these may be brought forward together with the bread and wine, but they are not to be placed on the altar.” —Wikipedia, Offertory

“73. At the beginning of the Liturgy of the Eucharist the gifts, which will become Christ’s Body and Blood, are brought to the altar. First, the altar, the Lord’s table, which is the center of the whole Liturgy of the Eucharist, is prepared by placing on it the corporal, purificator, Missal, and chalice (unless the chalice is prepared at the credence table). The offerings are then brought forward. It is praiseworthy for the bread and wine to be presented by the faithful. They are then accepted at an appropriate place by the priest or the deacon and carried to the altar. Even though the faithful no longer bring from their own possessions the bread and wine intended for the liturgy as in the past, nevertheless the rite of carrying up the offerings still retains its force and its spiritual significance. It is well also that money or other gifts for the poor or for the Church, brought by the faithful or collected in the church, should be received. These are to be put in a suitable place but away from the Eucharistic table.” —General Instruction of the Roman Missal, Paragraph 73

“The OFFERTORY of the Liturgy refers to the OFFERING of the Bread and Wine for the Eucharist–which historically is their actual placing on the altar, regardless of what other prayers or ceremonies accompanied this. Since nothing else can be the matter for the Eucharistic Sacrifice, besides bread and wine mingled with water, nothing else can be or should be on the altar. The Holy Oils are placed there since the are the matter of a Sacrament. Wedding rings are blessed on the altar since they are the emblem of a Sacrament. Perhaps tokens of other things, such as gifts for the poor, can be brought up — though not at the same time as the Eucharistic matter — to be blessed, but should NOT be placed on or near the altar, and should be removed immediately after this blessing.” —Catholic Answers Forum
