This feast was extended to Spain (1735); to Tuscany (double of the second class with an octave, 1807). After his return from his exile in France Pius VII extended the feast to the Latin Church (18 September, 1814), major double); it was raised to the rank of a double of the second class, 13 May, 1908. The Servites celebrate it as a double of the first class with an octave and a vigil. Also in the Passionate Order, at Florence and Granada (N.S. de las Angustias), its rank is double of the first class with an octave. The hymns which are now used in the Office of this feast were probably composed by the Servite Callisto Palumbella (eighteenth century). On the devotion, cf. Kellner, "Heortology", p. 271. The old title of the "Compassio" is preserved by the Diocese of Hildesheim in a simple feast, Saturday after the octave of Corpus Christi. A feast, "B.M.V. de pietate", with a beautiful medieval office, is kept in honour of the sorrowful mother at Goa in India and Braga in Portugal, on the third Sunday of October; in the ecclesiastical province of Rio de Janeiro in Brazil, last Sunday of May, etc. (cf. the corresponding calendars). A special form of devotion is practised in Spanish-speaking countries under the term of "N.S. de la Soledad", to commemorate the solitude of Mary on Holy Saturday. Its origin goes back to Queen Juana, lamenting the early death of her husband Philip I, King of Spain (1506).
To the oriental churches these feasts are unknown; the Catholic Ruthenians keep a feast of the sorrowful Mother on Friday after the octave of Corpus Christi. Text Source: The Catholic Encyclopedia
