Cyril (born Constantine, 826-869) and Methodius (815-885) were two brothers and Byzantine Christian theologians and missionaries. For their work evangelizing the Slavs, they are known as the "Apostles to the Slavs". They are credited with devising the Glagolitic alphabet, the first alphabet used to transcribe Old Church Slavonic. After their deaths, their pupils continued their missionary work among other Slavs. Both brothers are venerated in the Orthodox Church as saints with the title of "equal-to-apostles". In 1880, Pope Leo XIII introduced their feast into the calendar of the Roman Catholic Church. In 1980, Pope John Paul II declared them co-patron saints of Europe, together with Benedict of Nursia.
The Reverend Sabine Baring-Gould (28 January 1834 - 2 January 1924) of Lew Trenchard in Devon, England, was an Anglican priest, hagiographer, antiquarian, novelist, folk song collector and eclectic scholar. His bibliography consists of more than 1,240 publications, though this list continues to grow. His family home, the manor house of Lew Trenchard, near Okehampton, Devon, has been preserved as he had it rebuilt and is now a hotel. He is remembered particularly as a writer of hymns, the best-known being "Onward, Christian Soldiers", "Sing Lullaby", and "Now the Day Is Over". He also translated the carol "Gabriel's Message" from the Basque language to English.
