Which excerpt from the "General Prologue" of The Canterbury Tales tells us that the knight had been part of the Crusades, military expeditions in which Christians sought to win the Holy Land?
in Latvia raided he and Russia,
NO christened man so oft of his degree
in far Granada at the siege was he..
And he'd fought for our faith at Tramissene
Three times in lists, and each time slain his foe.
This self-same worthy Knight had been also
At one time with the lord of Palatye
And always won he sovereign fame for prize
house so lustrious, he was very wise
And borehmself as meekly as a maid.
