Three of the earliest Roman liturgical books, the Gelasian Sacramentary (7th c.), and both the Paduan (7th c.) and the Hadrian (8th c.) editions of the Gregorian Sacramentary already call the Sunday before Easter Dominica in Palmis ("Sunday for Palms") or Die dominico ad Palmas. Even so, none of these documents explicitly mention any observances of palm rites, which were by the time already being performed in various parts of Christendom. The references to palms is absent in the propers, and in all the Roman Epistolari and Evangeliari of the period - in fact, the original title for the day probably did not mention palms at all, since the rite did not probably reach Rome until about the tenth century. In Rome, Palm Sunday was simply Passion Sunday, due to the fact that the Passion account from Matthew's Gospel (chapters 26-27) was read on this day. After the Gospel is read, the pope then usually gave a sermon on the first half of the account, postponing his explanation of the remainder to the following Wednesday.
