The letter of Guibert to Lysiard

Some of my friends have often asked me why I do not sign this little
work with my own name; until now I have refused, out of fear of
sullying a pious history with the name of hateful person. However,
thinking that the story, splendid in itself, might become even more
splendid if attached to the name of a famous man, I have finally
decided to attach it to you. Thus I have placed a most pleasing lamp
in front of the work of an obscure author. For, since your ancient
lineage is accompanied by a knowledge of literature, as well an
unusual serenity and moral probity, one may justly believe that God
in his foresight wanted the dignity of the bishop's office to honor
the gift of such reverence. By embracing your name, the little work
that follows may flourish: crude in itself, it may be made agreeable
by the love of the one to whom it is written, and made stronger by
the authority of the office by which you stand above others.
