My introduction to courtly love was reading a Diana Wynne Jones novella (The True State of Affairs) that made no sense unless you know what courtly love is. After crawling confusedly through ancient Livejournal reviews to piece together what the story had been about, I took away that it was a weird medieval knight thing where you talk a lot of guff to a (married) woman without ever expecting it to turn into more than what it is.

The first chapter of CS Lewis’s The Allegory of Love explains the concept much more thoroughly. His account is pleasantly bonkers. I now relay it to you. (Note: not only am I skeptical of parts of his account, I read it while sleep deprived, so salt liberally.)

First, a sketch of the relationship:

The lover is always abject. Obedience to his lady’s lightest wish, however whimsical, and silent acquiescence in her rebukes, however unjust, are the only virtues he dares to claim. There is a service of love closely modelled on the service which a feudal vassal owes to his lord. The lover is the lady’s ‘man’. He addresses her as midons****, which etymologically represents not ‘my lady’ but ‘my lord’. The whole attitude has been rightly described as ‘a feudalisation of love’. This solemn amatory ritual is felt to be part and parcel of the courtly life.

This seems to have been both literary trope and a real-life interaction pattern (of which the former came first). A specific example in Arthuriana:

It is only later that [Lancelot] learns the cause of all this cruelty. The Queen has heard of his momentary hesitation in stepping on to the tumbril[, a humiliating cart he rode into the city where she was held captive, to rescue her], and this lukewarmness in the service of love has been held by her sufficient to annihilate all the merit of his subsequent labours and humiliations. Even when he is forgiven, his trials are not yet at an end. The tournament at the close of the poem gives Guinevere another opportunity of exercising her power. When he has already entered the lists, in disguise, and all, as usual, is going down before him, she sends him a message ordering him to do his poorest. Lancelot obediently lets himself be unhorsed by the next knight that comes against him, and then takes to his heels, feigning terror of every combatant that passes near him. The herald mocks him for a coward and the whole field takes up the laugh against him: the Queen looks on delighted. Next morning the same command is repeated, and he answers, ‘My thanks to her, if she will so’. This time, however, the restriction is withdrawn before the fighting actually begins.

So, huh. How did this cultural script come to be?

Courtly love as a literary trope began in 11th century Provence. Here’s Lewis’s sketch of that time and place:

We must picture a castle which is a little island of comparative leisure and luxury, and therefore at least of possible refinement, in a barbarous country-side. There are many men in it, and very few women—the lady, and her damsels. Around these throng the whole male meiny [i.e. attendants], the inferior nobles, the landless knights, the squires, and the pages—haughty creatures enough in relation to the peasantry beyond the walls, but feudally inferior to the lady as to her lord—her ‘men’ as feudal language had it. Whatever ‘courtesy’ is in the place flows from her: all female charm from her and her damsels. There is no question of marriage for most of the court. All these circumstances together come very near to being a ‘cause’; but they do not explain why very similar conditions elsewhere had to wait for Provençal example before they produced like results. Some part of the mystery remains inviolate.

So that’s the material background – a lopsided gender balance. But more fascinating is the cultural background where the passion and devotion of romantic love – a passion/devotion Lewis claims simply did not exist as a mode for men to treat women in Europe before courtly love was invented – could not be channeled into marriage because such a stance is incompatible with the social role of a husband:

The same woman who was the lady and ‘the dearest dread’ of her vassals was often little better than a piece of property to her husband. He was master in his own house. So far from being a natural channel for the new kind of love, marriage was rather the drab background against which that love stood out in all the contrast of its new tenderness and delicacy. The situation is indeed a very simple one, and not peculiar to the Middle Ages. Any idealization of sexual love, in a society where marriage is purely utilitarian, must begin by being an idealization of adultery.

In fact, courtly love’s rightful predecessor is not heterosexual love but the love of a vassal for his lord. (I am quite skeptical of this as a claim about reality, but less skeptical of it as a claim about literature.) Reiterating a sentence from the first quote in this post:

The whole attitude [of a knight in courtly love with his lady] has been rightly described as ‘a feudalisation of love’.

CS Lewis on that feudal relationship:

We shall never understand [the affection between vassal and lord], if we think of it in the light of our own moderated and impersonal loyalties. We must not think of officers drinking the king’s health: we must think rather of a small boy’s feeling for some hero in the sixth form. There is no harm in the analogy, for the good vassal is to the good citizen very much as a boy is to a man. … He loves and reverences only what he can touch and see; but he loves it with an intensity which our tradition is loath to allow except to sexual love.

So it’s that relationship that courtly love remixes into heterosexual romance. Courtly love ennobles the lover – there’s a religious parallel here for sure. And it is necessarily adulterous because marriage is not a matter of personal passion, because distance is conducive to recreational idealization, because the lack of potential sexual consummation is pleasantly purity-coded in a Christian society, and because a wife, being a knight’s inferior, cannot ennoble him. So, finally, Lewis says bluntly:

The love which is to be the source of all that is beautiful in life and manners must be the reward freely given by the lady, and only our superiors can reward. But a wife is not a superior.

Coming back briefly to Diana Wynne Jones’s The True State of Affairs: I understand much better now the behavior of the protagonist’s love interest. He’s a bored would-be king in captivity who decides to make the other visible prisoner his midons. He expects her to understand the convention he’s following. Why shouldn’t he take her on as a concept like this? She, also bored and deprived, benefits from his gifts and minor heroics. He wants an ennobling influence. And besides, isn’t idealizing a beautiful woman you never intend to make a move on fun?
