incitements of my friends, to whose suggestions, though only implied, I ought to pay regard: and they indeed gently urged me, already sufficiently disposed, to prosecute my undertaking. Animated, therefore, by the advice of those whom I love most affectionately, I advance to give them a lasting pledge of friendship from the stores of my research. Grateful also to those who are in fear for me, lest I should either excite hatred, or disguise the truth, I will, by the help of Christ, make such a return for their kindness, as neither to become odious, nor a falsifier. For I will describe, both what has been done well, or otherwise, in such wise, and so safely steer between Scylla and Charybdis, that my opinions shall not be concealed, though some matters may be omitted in my history. Moreover, to those who undervalue the labours of others, I make the same answer as St. Jerome formerly did to his critics; "Let them read if they like: if not, let them cast it aside; because I do not obtrude my work on the fastidious, but I dedicate it, if any think it worth their notice, to the studious;" which even these men will readily pronounce to be consonant to equity, unless they are of the number of those, of whom it is said; "Fools are easy to confute, but not so easy to restrain." I will relate, then, in this, the fourth book of my work, every thing which may be said of William, son of William the Great, in such manner that neither shall the truth suffer, nor shall the dignity of the prince be obscured. Some matters also will be inserted in these pages, which in his time were calamitous in this country, or glorious elsewhere, as far as my knowledge extends. More especially, the pilgrimage of the Christians to Jerusalem, which it will be proper to annex in this place; because an expedition, so famous in these times, is well worth hearing, and will also be an incitement to valour. Not indeed that I have any confidence these transactions will be better treated by me than by others who have written on the subject, but that, what many write, many may read. Yet, lest so long a preface should disgust my reader, I will immediately enter on my work.
