Kevin, a descendant of one of the ruling families in
Leinster, studied as a boy under the care of three holy men:
Eoghan, Lochan and Eanna. During this time, he went to Glendalough. He was to return later, with a small group of
monks to found a monastery where the 'two rivers form a confluence'. Kevin's writings discuss his fighting "knights" at Glendalough; scholars today believe this refers to his process of self-examination and his personal temptations. His fame as a holy man spread and he attracted numerous followers. He died in about
618, traditionally on 3 June. For the next six centuries, Glendalough flourished and the
Irish Annals contain references to the deaths of
abbots and raids on the settlement. Circa 1042, oak timber from Glendalough was used to build the second-longest
Viking longship recorded (circa 30 m). A modern replica of
that ship was built in 2004 and is currently located in
Roskilde, Denmark. At the
Synod of Rath Breasail in 1111, Glendalough was designated as one of the two
dioceses of North Leinster.
The Book of Glendalough was written there about
1131.
St. Laurence O'Toole, born in 1128, became
Abbot of Glendalough and was well known for his sanctity and hospitality. Even after his appointment as
Archbishop of Dublin in 1162, he returned occasionally to Glendalough, to the solitude of St. Kevin's Bed. He died in
Eu, in Normandy in 1180. by
Abraham Ortelius as "Glandalag". Descriptions of Glendalough from the 18th and 19th centuries include references to occasions of "riotous assembly" on the feast of St. Kevin on 3 June. The present remains in Glendalough tell only a small part of its story. The monastery in its heyday included workshops, areas for
manuscript writing and copying, guest houses, an infirmary, farm buildings and dwellings for both the monks and a large lay population. The buildings which survive probably date from between the 10th and 12th centuries. ==See of Glendalough==
