The highly evolved stone-age culture was absorbed and developed by the Celts when they settled in Ireland in the centuries before Christ. They in turn found it natural to accept Christianity which developed in a unique manner in such spiritual climate. Early hymns and liturgical texts, combining the older nature practice with the new religion of Christianity, bear witness to this unbroken evolution. Jakob Streit grew up in Spiez, Switzerland, a district to which Irish monks brought Christianity more than a thousand years ago. He studied natural history and the history of art. He is a teacher in child and adult education. Used Book in Good Condition
