Loyalty to a Woman

From Blanquerna by Ramon Llull:

Once upon a time a man loved a woman and said to her that he loved her more than any woman beside, and the woman enquired of him wherefore he loved her more than any other woman, and he replied that it was because she was fairer than any.

The woman made sign with her hand in a certain direction, saying that in that direction there was a woman that was fairer; and when the man turned and looked in that direction the woman said that if there were another woman that was fairer, he would love her more, and this signified that his love to her was not perfect.
