“Dame Amour” (English ‘Lady Love,’ or German ‘Frau Minne’) was a personified figure in medieval texts, especially by the French troubadours and trouvères, who were poets and singers who celebrated courtly love. They often addressed their beloved or the concept of love as “Dame Amour”, a female figure who represented the ideal and divine aspect of courtly love. She was also sometimes associated with the Virgin Mary, who was seen as the model of love and grace.
William IX, Duke of Aquitaine, who was the first known troubadour and the creator of courtly love, was the first person to use the phrase Dame Amour. He used this term to refer to his mistress, who was also his son’s wife. He wrote many poems dedicated to her, praising her beauty and grace.
One example of “Dame Amour” as a personification is in the poem “Lanquan li jorn” by the troubadour Jaufre Rudel, who expresses his longing for a distant lady whom he has never seen. He says:
Lanquan li jorn son lonc en mai m’es belhs dous chans d’auzelhs de lonh, e quan mi sui partitz de lai oblit mon chan e mon solonh; e quan mi sui partitz de vos no’m laissetz ges de chant ni de ris, que ja mais no’m chantet d’Amors ni de sa belha cortesia.
When the days are long in May I love the sweet song of the birds from afar, and when I have left there I forget my song and my joy; and when I have left you you leave me no song or laughter, for never again will Love sing to me or of her beautiful courtesy3
Here, “Amors” is a feminine noun that refers to both the emotion of love and the personification of “Dame Amour”, who is the source of the poet’s inspiration and happiness. He laments that he has lost her favor and her song, which implies that she is a musical and divine being who can communicate with him.

Note: Dame Amour (French) and Lady Love (English) represent the equivalent of the German Frau Minne, with each being the same personification and “goddess” of courtly love, but under a different title. This kind of love is a medieval invention which has no counterparts in the classical and ancient world.
