Those whose Altar Missal or Breviary dates from before 1962 will be familiar with the curious experience of realising, by seeing it in their books, that (e.g.) yesterday's S Andrew had, until very recently, a Vigil and a First Vespers. Whatever happened to them? Why are they nowhere to be seen in the 1962 books?
The tremendously Good News about Summorum Pontificum is that it has given seminarians and priests an enormous impulse to learn how to offer Mass according to the immemorially ancient Ordo Missae of the Roman Church.. If you, dear clerical reader, have learned how to do that, you don't need me to tell you that you have acquired a pearl of great price. But what is often not realised is that, as far as the Calendar is concerned, '1962' constituted a a very considerable break in continuity. You see, the process which led to the imposition in 1970 of the Novus Ordo did not start after 'the Council'; it had begun a couple of decades earlier when Pius XII and his youthful protege Annibale Bugnini set out on a two-decade journey to the Novus Ordo. During that period, Vigils and Octaves galore bit the dust; but perhaps the most questionable 'reform' of all was the abolition of First Vespers for all but the highest rank of festivals. This abolished the ancient Christian practice, inherited from the Synagogue, of starting a day on the previous evening.
What I am urging you to purchase, if you are not already familiar with it, is the Saint Lawrence Press ORDO for 2017. OK, you may very well not wish to follow it liturgically, but simply contemplating, day by day, what the old Roman Rite did before itching and twitching fingers got to work on it, is, believe me, a considerable education.
UPDATE: THE COMPILER HAS KINDLY PROVIDED A LINK FOR PURCHASERS. SEE THE THREAD. This ORDO can be sought from email@example.com; or from 59 Sandscroft Avenue, Broadway, Worcestershire, WR12 7EJ, United Kingdom.
The Compiler of that ORDO also runs a blog explaining the pre-Pius XII Roman Rite the st lawrence press blog.
If 'Tridentine' is to refer to the actual liturgical books of S Pius V, as I think it probably should, then you can find out about the Tridentine Rite by looking at another blog by the same erudite author, called The Tridentine Rite. There you will discover that the Common Preface is (I mean, in the Missal actually issued by S Pius V) used on these green Sundays! You will also, I suspect, be surprised by some of the rather Puritanical prunings of the Calendar: for example, the elimination of 'non-biblical' feasts such as S Anne and the Presentation of our Lady. They soon returned, by popular demand; but they had sunk without trace under Pius V.
And the Office Hymns of S Pius V, of course, will not be those with which users of the 1962 Breviary are familiar. Those texts were produced in the 1620s by Urban VIII, aka Papa Barberini. The breviary of S Pius V had the ancient texts, sometimes totally different from the Barberini versions, which one will also find in the Sarum and Benedictine Breviaries.
