Gabriel's horn also makes an appearance in "The Eyes of Texas" (1903) where it signifies the rapture. In Marc Connelly's play based on spirituals, "The Green Pastures" (1930), Gabriel has his beloved trumpet constantly with him, and the Lord has to warn him not to blow it too soon. Four years later "Blow, Gabriel, Blow" was introduced by Ethel Merman in Cole Porter's "Anything Goes" (1934). Saint Gabriel the Archangel's festival day was exclusively celebrated on 18 March according to many sources dating between 1588 and 1921; unusually, a source published in 1856 has the feast celebrated on 7 April for unknown reasons (a note in parentheses states that the day is normally celebrated on 18 March). Writer Elizabeth Drayson mentions the feast being celebrated on 18 March 1588 in her 2013 book "The Lead Books of Granada". One of the oldest out of print sources placing the feast on 18 March, first published in 1608, is "Flos sanctorum: historia general de la vida y hechos de Jesu-Christo ... y de los santos de que reza y haze fiesta la Iglesia Catholica ..." by the Spanish writer Alonso de Villegas; a newer edition of this book was published in 1794. Another source published in Ireland in 1886 «The Irish Ecclesiastical Record» also mentions March 18. There is a painting from 1886 by the Italian artist Diodore Rahoult, on which 18 March also appears. The feast of Saint Gabriel was included by Pope Benedict XV in the General Roman Calendar in 1921, for celebration on 24 March. In 1969 the day was officially transferred to 29 September for celebration in conjunction with the feast of the archangels St. Michael and St. Raphael. The Church of England has also adopted the 29 September date, known as Michaelmas. The Eastern Orthodox Church and those Eastern Catholic Churches which follow the Byzantine Rite celebrate his feast day on 8 November (for those churches that follow the traditional Julian Calendar, 8 November currently falls on 21 November of the modern Gregorian Calendar, a difference of 13 days). Eastern Orthodox commemorate him, not only on his November feast, but also on two other days: 26 March is the "Synaxis of the Archangel Gabriel" and celebrates his role in the Annunciation.  13 July is also known as the "Synaxis of the Archangel Gabriel", and celebrates all the appearances and miracles attributed to Gabriel throughout history. The feast was first established on Mount Athos when, in the 9th century, during the reign of Emperor Basil II and the Empress Constantina Porphyrogenitus and while Nicholas Chrysoverges was Patriarch of Constantinople, the Archangel appeared in a cell near Karyes, where he wrote with his finger on a stone tablet the hymn to the Theotokos, "It is truly meet...".
