Arawn and Pwyll: Trust, Exchange and the Making of a Friendship

What happens when we are entrusted with something that belongs to another?

The meeting between Pwyll and Arawn begins badly.

There is no careful approach to the Otherworld, no exchange of gifts, and no moment in which Pwyll knowingly seeks the favour of its king. Instead, there is a hunt in the woods of Dyfed, a fallen stag, and an act of discourtesy that sets one of the most compelling relationships in the First Branch of the Mabinogi in motion.

What follows is a story of two rulers exchanging places and carrying one another's responsibilities for a year. Yet beneath the supernatural elements lies a quieter question: what do we do when another person places something valuable in our keeping?

It is a story I return to when thinking about reciprocity, responsibility and fair exchange in my own practice. Before it becomes a source of contemporary reflection, however, it deserves to be met on its own terms.

The First Branch of the Mabinogi

The story of Pwyll and Arawn forms the opening movement of Pwyll Pendefig Dyfed — Pwyll, Prince of Dyfed — the First Branch of the Mabinogi.

The tales now commonly encountered under the broader title The Mabinogion are medieval Welsh prose narratives preserved principally in the White Book of Rhydderch, copied around the middle of the fourteenth century, and the later Red Book of Hergest. The stories themselves draw upon older traditions, but the surviving texts belong to medieval Wales, and we should be cautious about treating them as transparent records of a much earlier pre-Christian religion.

Pwyll enters the story as prince of Dyfed. While hunting at Glyn Cuch, he becomes separated from his companions and encounters another pack of hounds pursuing a stag. These are no ordinary hunting dogs: their bodies are shining white and their ears red.

When the strange hounds bring down the stag, Pwyll drives them away and allows his own dogs to feed upon their kill. Only afterwards does the owner of the other pack appear.

He is Arawn, king of Annwfn.

Annwfn is sometimes described simply as an underworld, although the Welsh Otherworld is more complicated than that description suggests. Medieval Welsh literature does not give us a single, tidy geography of the realm, and I think it is better to allow some of that uncertainty to remain. What matters here is that its king has crossed Pwyll's path in the landscape of Dyfed, and Pwyll has treated him discourteously.

Arawn makes his displeasure clear. Pwyll has taken what another hunt rightfully won.

Pwyll's response is important. Once the offence is explained to him, he does not argue over his intentions or attempt to make the matter smaller. Instead, he asks Arawn how he might make amends.

Arawn has an answer.

An exchange of places

Arawn tells Pwyll of Hafgan, another king in Annwfn who stands against him, and proposes an extraordinary arrangement.

For a year and a day, Pwyll will take Arawn's appearance and live in Annwfn in his place, while Arawn assumes Pwyll's appearance and governs Dyfed. Nobody in either realm will recognise that an exchange has taken place.

At the end of that period, Pwyll must meet Hafgan at a ford. Arawn instructs him to strike Hafgan once and, however much the wounded king might ask for another blow, never to strike him a second time.

Pwyll agrees.

It is easy to concentrate upon the supernatural transformation here, but the degree of trust involved interests me far more. Arawn is not merely giving Pwyll a task to complete on his behalf. He is entrusting him with his identity, his court, his authority, his household and the responsibilities of his kingship. Pwyll, in turn, leaves Dyfed and everything attached to his own position in Arawn's hands.

For most of the following year, the people around them have no idea that anything has changed.

Each man therefore receives temporary possession of a life that is not his own, and much of the meaning I find in their exchange lies in what they choose to do with it.

What we do with another person's trust

Pwyll enters Arawn's court and finds himself surrounded by hospitality and abundance. He takes his place within the household, eating, drinking and speaking with the queen as though he truly were its king.

During the day, Pwyll and Arawn's wife converse warmly. At night, however, he turns away from her. He continues to do so throughout his time in Annwfn.

The detail matters because everyone around Pwyll believes that he is Arawn. He has been given the appearance and authority of another man, but he does not treat that appearance as permission to take everything belonging to the life he has temporarily entered.

When the appointed meeting with Hafgan finally arrives, Pwyll again honours the terms under which Arawn placed his trust in him. He gives Hafgan the single blow he was instructed to give and, when the wounded king asks him to strike again, refuses.

Pwyll does not rewrite the agreement when circumstances make another choice possible. He does what he promised to do.

Hafgan can no longer maintain his rule, and his people acknowledge the man they believe to be Arawn. Pwyll has therefore accomplished what was asked of him, but the exchange has never been one-sided. Throughout the same year, Arawn has been carrying Pwyll's responsibilities in Dyfed.

Arawn in Dyfed

At the end of the year, Pwyll and Arawn meet again, regain their own appearances and return to their respective realms.

When Pwyll arrives home, he learns something that could easily have wounded a less thoughtful ruler's pride.

The people of Dyfed have been very pleased with him.

Or rather, they have been pleased with the man they believed was him.

During the year in which Arawn governed in Pwyll's place, he had shown good judgement, generosity and care towards Pwyll's people. Their prince seemed to them to have become a better ruler than he had been before he left, although they had no way of knowing that another man had been occupying his place.

I find this one of the quieter but more interesting consequences of the exchange. Pwyll does not simply return to find his kingdom safely preserved. He returns having been shown another way of inhabiting his own responsibilities.

For a year, somebody else has stood where he normally stands and demonstrated what his rule might look like when exercised differently. Pwyll is given an unusual opportunity to see his own position from the outside, and the comparison offers something more useful than praise: it gives him something from which he can learn.

The exchange has therefore changed more than the balance of power in Annwfn. It has also allowed Pwyll to return to Dyfed with a different understanding of the role he already held.

Friendship after obligation

Arawn, meanwhile, makes a discovery of his own.

When he returns to his wife, he learns that Pwyll never took advantage of the place he had been given beside her. Arawn can now know how Pwyll behaved during a year in which Pwyll had every reason to believe that his private conduct would remain unseen.

Their relationship deepens after this.

Pwyll and Arawn continue as friends, exchanging horses, hunting dogs, hawks and other treasures they believe will please one another. Pwyll's association with the Otherworld becomes significant enough that he acquires the title Pwyll Pen Annwfn — Pwyll, Head of Annwfn.

Their friendship is therefore not simply announced by the telling. It has been built through what came before it.

Pwyll's original offence is acknowledged and a means of reparation is accepted. Arawn extends trust, Pwyll accepts the responsibility that comes with it, and both men take care of what has temporarily been placed in their hands. Boundaries are respected, agreements are kept, and what begins as an uncomfortable meeting in the woods eventually develops into an enduring friendship in which gifts continue to pass freely between them.

That progression is worth noticing, particularly when we think about what reciprocity might mean beyond a simple exchange of one thing for another.

Reciprocity is more than giving

In contemporary spiritual practice, reciprocity is sometimes reduced to a fairly simple idea: when we receive something, we should remember to give something back.

There is value in that principle. Yet the relationship between Arawn and Pwyll offers me a more interesting way to think about exchange because neither man's responsibility ends with repayment.

For a time, each is asked to take care of something belonging to the other.

Arawn does not merely keep Dyfed intact until Pwyll returns. He governs it well. Pwyll does not merely defeat Hafgan and consider his obligation fulfilled. Throughout his time in Annwfn, he remains conscious that the authority and relationships surrounding him are not truly his to exploit.

Neither treats temporary possession as ownership.

That idea reaches considerably further than the exchange of gifts. We are continually receiving things that place us in relationship with other people and with the world around us: another person's confidence, somebody's time, knowledge handed down to us, materials gathered from a landscape, stories inherited through a culture, or resources earned through the labour of ourselves and others.

Receiving any of these things may create responsibilities that cannot be measured neatly by asking what we owe in return.

Sometimes reciprocity begins with tending well what has reached our hands.

Reading an old story without making it say too much

Stories from the Mabinogi invite interpretation, but they also deserve some resistance to our desire to make every detail useful.

It would be easy to take the white-and-red hounds, the year and a day, the ford where Hafgan is struck, and Arawn's kingship in Annwfn and turn each of them into a fixed magical correspondence. With enough interpretation, the medieval narrative could soon begin to resemble a ritual handbook that it never claimed to be.

I prefer to leave more room around the story.

The First Branch does not preserve Arawn's Current, nor does it present Arawn as a straightforward Welsh god of prosperity or wealth. Within this story he is Arawn, king of Annwfn, and there is value in allowing him to remain that before asking what his story might mean within a contemporary spiritual practice.

This does not prevent old stories from informing new work. It simply asks us to remain aware of where the older material ends and our own interpretation begins.

For me, that changes the question.

Rather than asking what secret practice might be hidden within the First Branch, I find it more useful to ask what the story has taught me to notice.

From the story into contemporary practice

My own work with Arawn has been shaped partly by this understanding of exchange, and it is one of the threads from which I developed Arawn's Current, a contemporary rite concerned with prosperity, livelihood and the circulation of resources.

The rite is not something I claim to have recovered from the Mabinogi. It belongs to my contemporary practice, informed by the relationship I have developed with Welsh stories and by the questions those stories continue to raise for me.

Among those questions is what we actually mean when we ask for prosperity.

I do not understand prosperity simply as acquiring more. Money is earned and spent; work is offered and compensated; knowledge is received and shared; resources pass between people and through households. We live within networks of exchange involving other people, places, materials and systems that existed before us and will continue after us.

Seen in that way, the question is no longer only What would I like to receive?

We might also ask what we are already being trusted to carry, whether we are tending it well, where an exchange in our lives has become unbalanced, and what would genuinely constitute enough for the work before us.

Those are contemporary questions, and I would not place them in the mouths of medieval Welsh storytellers. The relationship between Pwyll and Arawn simply gives me a language through which to consider them.

Arawn entrusts something valuable to Pwyll, while Pwyll entrusts something equally valuable to Arawn. Neither is diminished by caring well for what belongs to the other. Instead, two strangers whose first meeting is marked by discourtesy eventually become friends because of what happens after that mistake.

Perhaps this is one reason the opening of the First Branch continues to reward another reading.

It does not promise that every exchange will be equal, that generosity guarantees reward, or that careful conduct will always be recognised. What it offers is quieter: a reminder that what passes through our hands can still deserve our care even when it will not remain with us.

Sometimes the measure of an exchange is not what we manage to keep, but the condition in which we leave what was entrusted to us.
