PREFACE. This new edition of the Mythology of Greece and Italy is properly speaking a new work. Few pages or even paragraphs remain unaltered, and nearly two-thirds of it are new matter, or have been rewritten. The causes of this change (of which I think an explanation is due) are as follows. The work was originally intended to be a mere school-book, and it was commenced on that plan ; circumstances caused it to be continued on another, and to be completed on a third ; hence the inequality in it which every one must have observed.
