This book is an account, or various accounts, of the life and work of one of Galicia's most important figures during the second half of the twentieth century, with special relevance to the pilgrimage to Santiago de Compostela. He came to be universally know as "the priest of O Cebreiro", but his name was Elías Valiña Sampedro. He was born into a well-off farming family and trained for the priesthood in Lugo's diocesan seminary, after which he spent the rest of his life in the tiny village of O Cebreiro in the rugged part of the province knows as "Alta Montaña", demostrating that the concentrated application of intelligence and hard work could indeed move mountains.
