user: Information:  - Saint Columba ('church dove'; 7 December 521  9 June 597) was an Irish abbot and missionary credited with spreading Christianity in what is today Scotland at the start of the Hiberno-Scottish mission. He founded the important abbey on Iona, which became a dominant religious and political institution in the region for centuries. He is the Patron Saint of Derry. He was highly regarded by both the Gaels of Dál Riata and the Picts, and is remembered today as a Christian saint and one of the Twelve Apostles of Ireland.  - The Hiberno-Scottish mission is a generic title given to a series of missions and expeditions initiated by various Irish clerics and cleric-scholars who, for the most part, are not known to have acted in concert. There was no overall coordinated mission, but there were nevertheless sporadic missions initiated by Gaelic monks from Ireland and the western coast of modern-day Scotland, which contributed to the spread of Christianity and established monasteries in Britain and continental Europe during the Middle Ages. The earliest recorded Irish mission can be dated to 563 with the foundation of Iona by the Irish monk Saint Columba. Columba is said by Bede and Adamnán to have ministered to the Gaels of Dál Riada and converted the northern Pictish kingdoms. Over the next centuries more missions followed and spread through Anglo-Saxon England and the Frankish Empire. The early missions are often associated with the Christian practice known as Celtic Christianity, which was distinguished by its organizations around monasteries rather than dioceses and certain idiosyncratic traditions, but the desire to maintain a relationship with the Holy See saw their missions take on a more Roman character.  - Columbanus (543  21 November 615), also known as St. Columban, was an Irish missionary notable for founding a number of monasteries from around 590 in the Frankish and Lombard kingdoms, most notably Luxeuil Abbey in present-day France and Bobbio Abbey in present-day Italy. He is remembered as a key figure in the Hiberno-Scottish mission, or Irish missionary activity in early medieval Europe. In recent years, however, as Columbanus's deeds and legacy have come to be re-examined by historians, the traditional narrative of his career has been challenged and doubts have been raised regarding his actual involvement in missionary work and the extent to which he was driven by purely religious motives or also by a concern for playing an active part in politics and church politics in Francia.  - Bobbio Abbey (Italian: "Abbazia di San Colombano") is a monastery founded by Irish Saint Columbanus in 614, around which later grew up the town of Bobbio, in the province of Piacenza, Emilia-Romagna, Italy. It is dedicated to Saint Columbanus. It was famous as a centre of resistance to Arianism and as one of the greatest libraries in the Middle Ages, and was the original on which the monastery in Umberto Eco's novel "The Name of the Rose" was based, together with Sacra di San Michele. The abbey was dissolved under the French administration in 1803, although many of the buildings remain in other uses.  - Atala or Attala ( died 622 ) was a disciple of Columbanus and his successor as abbot of Bobbio from 615 . Attala was originally from Burgundy , and first became a monk at the abbey of Lérins . Displeased with the loose discipline prevailing there , he instead entered the abbey of Luxeuil , which had just been founded by Columbanus . When the latter was expelled from Luxeuil by King Theuderic II , Attala would have succeeded him as abbot , but preferred to follow him into exile . They settled on the banks of the river Trebbia , a little northeast of Genoa , where they together founded Bobbio . After the Columbanus ' death in 615 , Attala succeeded him as abbot . He and his monks suffered many hardships at the hands of King Arioald , who was an Arian and not a Catholic . As abbot , Attala insisted on strict discipline and when a large number of his monks rebelled , declaring his discipline too rigorous , he permitted them to leave the monastery . According to Attala 's biographer , Jonas , when some of these monks perished miserably , the others considered their deaths a punishment from God and returned to the monastery . Attala also restored the binding of the books in the monastic library . A surviving palimpsest copy of the works of Ulfilas bears the inscription `` a book from the cupboard of lord Atala '' ( l ( iber ) de arca domno atalani ) . Attala was buried in Bobbio , where his liturgical feast is celebrated on 10 March .    'saint attala' is related to which object entity through the relation of 'occupation'?
