ACKNOWLEDGEMENTS
A number of medieval historians were kind enough to share their
thoughts on certain points featured in this book and for their com-
munications I would like to thank Anne Duggan, S. B. Edgington,
John France, Bernard Hamilton, Natasha Hodgson, A. V. Murray and
Leena Roos. Sini Kangas was particularly supportive and brought her
extensive knowledge of the First Crusade to bear on the early drafts
of some of the chapters.
The formulations in this book have benefi ted greatly from their hav-
ing been discussed with my colleagues at Trinity College Dublin; my
thanks are due to Terry Barry, Léan Ní Chléirigh, Peter Crooks, Séan
Duffy, David Green, Katherine Simms and all those who attended the
seminars at which some of the ideas in this book were fi rst presented.
Most heartfelt thanks are especially due to Christine Meek, whose
extensive bibliographical knowledge was extremely helpful and who
was very generous with her time.
It has been a great pleasure to work with such effi cient, friendly and
supportive librarians as Anne Walsh and Mary Higgins at the Library
of Trinity College Dublin. Alas, since I wrote the preceding sentence
Anne passed away: this book is dedicated to her memory.
Much of the research for this book was conducted while I was a
post-graduate scholar of the Irish Research Council for the Humanities
and the Social Sciences and I am very grateful for their assistance.
I was fortunate in growing up in a household where medieval history
was frequently a topic for discussion, a topic informed by my father’s
extensive and scholarly book collection, much of which has stealthily
been transferred over the years to my own bookshelves. The impact on
this book of conversations with my father, Gerry Kostick, and especially
my brother, Gavin Kostick, has been considerable.
Two other non-medievalists who I am keen to acknowledge here for
their moral and intellectual support are my old comrade Andy Wilson
and my partner Aoife Kearney.
Finally, I turn to I. S. Robinson. If I were to do justice to the kind-
ness, intellect, erudition and generosity of my former supervisor this
acknowledgement would both embarrass him and sound distinctly like
this was a work of medieval hagiography. I therefore confi ne myself to
saying that no scholar could have wanted for a better mentor.
