Introduction
To the Most Excellent and Most Christian Lord Louis, by the Grace of GOD the illustrious King of the French; Friar William de Rubruquis, the meanest of the Minorite Order, wisheth health and continual triumph in CHRIST JESUS.
It is written in the book of Ecclesiasticus, "That the truly wise man shall travel through strange countries; for he hath tried the good and evil among men." All this, Sire, I have performed; and I wish I may have done so as a wise man, and not as a fool. For many do foolishly those things which have been done by wise men, and I fear I may be reckoned among that number.
But as you were pleased to command me at my departure, that I should write down every thing I saw among the Tartars, and should not fear to write long letters, I now therefore obey your orders, yet with awe and reverence, as wanting fit language in which to address so great a king.
