Book excerpt: This is the third revision of this seminal work. Co-authored by original author Frank Mitchell and now Michael Ryan, the result is a stunning collaboration between masters giving all the elements of the original book, modified, updated and further enhanced by the inclusion of a new narrative of Irish archaeology from the Stone Age to the Norman Invasion. Together they have successfully undertaken the daunting task of giving in one book the story of the shaping of the land from the beginning of time until now, by all tbe varying forces of nature, sea, climate, man and machine. The story takes in the shaping of the crust, the movement of glaciers, the first men and their primitive agriculture, their buildings and their effect on the forests, the growth of bogs, new migrations, the rise of the monasteries of the Early Christians and the castles of conquest, the devastation of war, urban growth, modern agriculture and afforestation, all set against the backdrop of the landscape, arguably one Ireland's most precious resources.
