Some, particularly champions of Christianity, hold the 6th to 9th centuries to be a Golden Age for the Gaels. This is due to the influence which the Gaels had across Western Europe as part of their Christian missionary activities. Similar to the Desert Fathers, Gaelic monastics were known for their asceticism. Some of the most celebrated figures of this time were Columba, Aidan, Columbanus and others. Learned in Greek and Latin during an age of cultural collapse, the Gaelic scholars were able to gain a presence at the court of the Carolingian Frankish Empire; perhaps the best known example is Johannes Scotus Eriugena. Aside from their activities abroad, insular art flourished domestically, with artifacts such as the Book of Kells and Tara Brooch surviving. Clonmacnoise, Glendalough, Clonard, Durrow and Inis Cathaigh are some of the more prominent Ireland-based monasteries founded during this time.
