In May 2013 it was 1450 years since the arrival on Iona of Columba, the imperious and energetic Irishman of royal descent who founded its famous monastery and became Scotland's best-known Celtic saint. To celebrate this important anniversary, Iona Cathedral Trust has commissioned a new book by the historian Rosalind K. Marshall. Using a wide variety of sources and taking into account the results of the most recent historical and archaeological research, she charts the many developments on Iona throughout the centuries, investigating why it has had such an enduring influence on Scottish life. With 32 color and b&w plates.
