This book was a pleasure to read both before and after reading PARADISE LOST. In fact, one can make a nice trilogy out of PREFACE TO PARADISE LOST, PARADISE LOST, and Lewis's PERELANDRA. Lewis's PREFACE should interest both the general reader and the specialist. Lewis gives a roadmap for working through Milton's epic poem, discussing what an epic is and why Milton chose it, for example, or why Milton used a certain style for writing; he also comments on Milton's theology, medieval hierarchy, and a number of other pertinent subjects with which the reader will probably not be overly familiar. The writing is clear, the discussion lucid and enlightening, and the subjects are interesting. This is certainly worth purchasing.
