In the Middle Ages, the troubadour poets invented the concept of courtly love--a fantasy love, a noble passion, which was also extra-marital and thus inevitably thwarted, illicit, adulterous. One of the medieval terms for it was amour honestus (honest love). I've always wondered why this passionate ideal--masochistic, spiritual-travelled with such wildfire throughout Europe. My poem, a ghazal, takes up the subject.
