Columbanus [PDF ebook] 
Poet, Preacher, Statesman, Saint

Columbanus ("The Dove of the Church"), not to be confused with his near-contemporary Columba of Iona, was a towering figure in the religious and political life of Europe in the Dark Ages. In this lively biography of the saint, Carol Richards evokes the violent and unstable age that laid the foundations for the achievements of the Middle Ages.
