|It was ALL about Lust - Not "Love"!|
Courtly love seems to have been to a considerable extent a literary invention (this proving once again that writers are in general a foolish and empty-headed lot) although the increasing feminisation of the Church and the rise and rise of the cult of Mary may have played a part. In any case courtly love spread like wildfire through the upper classes. Or to be more precise, it spread like wildfire among the women of the upper classes.
At the time it was perhaps not entirely a bad idea, or it didn’t seem like such a terrible idea.
