Guillaume Dufay
Veni Sancte Spiritus
Traditional Catholics should in particular remember those calendar features that the 1968-1969 liturgist brigade tried to eradicate based on an antihistorical and false antiquarianism: Septuagesimatide, Ember Days, the Pentecost Octave... That is, the committeemen kept the octave day itself (the Feast of the Most Holy Trinity), but eliminated the days of the Octave - though the former is much less ancient than the latter. This great and ancient Octave even has its own Ember Days: if you have the chance, celebrate the Holy Ghost by attending weekday Masses during this Octave. And, if you do not have weekday TLMs available near you, there is always the great FSSP apostolate at LiveMass.org.
