What had previously been called matins was given the name of "office of readings" ("officium lectionis") and was declared appropriate for celebrating at any hour, while preserving its nocturnal character for those who wished to celebrate a vigil. For that purpose alternative hymns are provided and an appendix contains material, in particular canticles and readings from the Gospels, to facilitate celebration of a vigil. The Catholic Church has thus restored to the word "vigil" the meaning it had in early Christianity. Pope John XIII's "Code of Rubrics" still used the word "vigil" to mean the "day before" a feast, but recognized the quite different character of the Easter Vigil, which, "since it is not a liturgical day, is celebrated in its own way, as a night watch". The Roman liturgy now uses the term "vigil" either in this sense of "a night watch" or with regard to a Mass celebrated in the evening before a feast, not before the hour of First Vespers.
