The Roman or Pontifical Indiction began on the 25th of December or 1st of January, according as the Christian year was held to begin on the one or other of these days.
As to its style, the Christian Year is calm and grave in tone, and subdued in colour, as beseems its subjects and sentiments.
Hence the first eight months of the Christian year coincide with the Constantinopolitan year 5509, while the last four months belong to the year 5510.
On Easter Eve the new fire, symbol of the light of the newly risen Christ, is produced, and from this are kindled all the lights used throughout the Christian year until, in the gathering darkness (tenebrae) of the Passion, they are gradually extinguished.
The Proprium de Tempore contains the office of the seasons of the Christian year (Advent to Trinity), a conception that only gradually grew up. There is here given the whole service for every Sunday and week-day, the proper antiphons, responsories, hymns, and especially the course of daily Scripture-reading, averaging about twenty verses a day, and (roughly) arranged thus: for Advent, Isaiah; Epiphany to Septuagesima, Pauline Epistles; Lent, patristic homilies (Genesis on Sundays); Passion-tide, Jeremiah; Easter to Whitsun, Acts, Catholic epistles and Apocalypse; Whitsun to August, Samuel and Kings; August to Advent, Wisdom books, Maccabees, Prophets.
