Question: What is the name of the Christian saint who founded the monastery where Cædmon cared for the animals?
Context: Saint Mechtilde of Hackeborn (1240/1241 – 19 November 1298) was a Saxon Christian saint (from what is now Germany) and a Benedictine nun.  In the modern Benedictine calendar, her feast is celebrated on the anniversary of her death, November 19.  She died in the monastery of Helfta. Anselm (died 805), the Duke of "Forum Julii" in the northeastern part of Lombard Italy, left the world at the height of his secular career, and in 750 built a monastery at Fanano, a place given to him by Aistulf, King of the Lombards, who had married Anselm's sister Gisaltruda.  Two years later he built the monastery of Nonantula, a short distance northeast of Modena, which Aistulf endowed.  Anselm went to Rome, where Pope Stephen III invested him with the habit of Saint Benedict, gave him some relics of Saint Sylvester and appointed him Abbot of Nonantula.  Anselm founded many hospices where the poor and the sick were sheltered and cared for by monks. The Monastery of Saint Matthew the Potter, also known as the Monastery of Saint Matthew the Poor, is a Coptic Orthodox monastery in Upper Egypt.  It was founded by a Coptic monk of the same name.  It is located in Luxor Governorate near the town of Naq 'al-Zinaiqa, about seven kilometers northwest of the village of Asfun al-Matana near Esna.  The monastery is built at the edge of the desert.  It was uninhabited for a period of time, but in 1975, Coptic Orthodox monks reestablished a presence there.  Excavations done by French archeologists between the Monastery of Saint Matthew the Poor and the Monastery of the Martyrs have revealed much about the history of Coptic monasticism in this region. Saint Matthew the Potter, also known as Saint Matthew the Poor, is an Egyptian Christian saint of the 8th century.  He was contemporary of Pope Alexander II of Alexandria (704 AD - 729 AD).  According to Abu Salih the Armenian, Saint Matthew the Potter may have also been Coptic Orthodox bishop of the city of Esna.  He is the founder of the Monastery of Saint Matthew the Potter. Gabra Manfas Qeddus (Amharic: ገብረ መንፈስ ቅዱስ; also familiarly called Abo) was an Ethiopian Christian saint, and the founder of the monastery of Zuqualla.  The fifth day of every month in the Ethiopian calendar is dedicated to this saint. The Monastery of Saint Anthony is a Coptic Orthodox monastery standing in an oasis in the Eastern Desert of Egypt, in the southern part of the Suez Governorate.  Hidden deep in the Red Sea mountains, it is located 334 km southeast of Cairo.  It is the oldest monastary in the world.  St Anthony himself was the founder of monasticism.  The Monastery of Saint Anthony was established by the followers of Saint Anthony, who is the first Christian monk.  The Monastery of St. Anthony is one of the most prominent monasteries in Egypt and has strongly influenced the formation of several Coptic institutions, and has promoted monasticism in general.  Several patriarchs have come from the monastery, and several hundred pilgrims visit it each day. The Rmanj Monastery () is a Serbian Orthodox monastery dedicated to Saint Nicholas and located in Martin Brod in north-western Bosnia and Herzegovina, at the left bank of the Unac River near its confluence with the Una.  It was probably founded in the late 15th or early 16th century.  After the Ottoman Empire's conquest of the area, the monastery was temporarily abandoned in 1578.  Bosnian Beylerbey Telli Hasan Pasha had the Rmanj Monastery renewed as a seat of his brother, Orthodox monk Gavrilo Predojević.  In the early 17th century, it became the see of the Serbian Orthodox Metropolitanate of Dabar-Bosnia, and it remained in this capacity for about 110 years.  After the monastery was burned down by the Turks in 1663, it was later rebuilt and reoccupied in 1737.  It was burned down again during the Austro-Turkish War of 1787–1791.  Ottoman authorities allowed the renovation of the monastery in 1863, and it was rebuilt in two years.  It was badly damaged during the anti-Ottoman uprising in Bosnia in 1875 and 1876.  Next year, Arthur Evans visited Rmanj (spelled as "Ermanja" by him), and in one of his letters, he described the damage inflicted on the monastery's church by troops under a Bosnian Muslim feudal lord.  Once more, the monastery was repaired in 1883. Cædmon ( or ; "fl.  c." AD 657–684) is the earliest English (Northumbrian) poet whose name is known.  An Anglo-Saxon who cared for the animals at the double monastery of Streonæshalch (Whitby Abbey) during the abbacy (657–680) of St. Hilda (614–680), he was originally ignorant of "the art of song" but learned to compose one night in the course of a dream, according to the 8th-century historian Bede.  He later became a zealous monk and an accomplished and inspirational Christian poet. Saint Stephen's Day, or the Feast of Saint Stephen, is a Christian saint's day to commemorate Saint Stephen, the first Christian martyr or protomartyr, celebrated on 26 December in the Latin Church and 27 December in Eastern Christianity.  The Eastern Orthodox Church adheres to the Julian calendar and mark Saint Stephen's Day on 27 December according to that calendar, which places it on 9 January of the Gregorian calendar used in secular contexts.  In Latin Christian denominations, Saint Stephen's Day marks the second day of Christmastide. Hilda of Whitby or Hild of Whitby (c. 614–680) is a Christian saint and the founding abbess of the monastery at Whitby, which was chosen as the venue for the Synod of Whitby.
