Arawn

Arawn enters Welsh tradition in the first branch of the Mabinogi, and his opening scene is a quarrel about manners. Pwyll, prince of Dyfed, drives another hunter's hounds off a stag they have brought down and sets his own pack on it; the wronged huntsman is Arawn, a crowned king of Annwn, and he names the discourtesy for what it is. The amends he sets become the frame of the whole tale: the two exchange shapes and kingdoms for a year, and at the year's end Pwyll, wearing Arawn's form, must meet Havgan — Arawn's rival among the kings of Annwn — and fell him with a single blow, striking no second. Pwyll keeps every term of the bargain, and the two kings part as lasting friends, their realms bound by the exchange.

His hounds are the tradition's most vivid possession. They are described as shining white with red ears, the whiteness and the redness equally striking — the standard livery of Celtic otherworld animals — and they course between the worlds. In later Welsh belief this pack, the Cwn Annwn, drifted toward the terrible: hounds heard in the air at night, held by some to hunt the souls of the wicked. Annwn itself, as the Mabinogion draws it, is not a hell but the classic Celtic otherworld: beautiful, unchanging, without pain, disease, or death, its court given over to feasting and games.

Arawn's dealings with this world run through gifts and thefts of animals. He owned a magical cauldron, a possession that has invited comparison with the Irish father god the Dagda, and magical pigs, given by him to Pryderi, the mortal king; the bard Gwydion's theft of those pigs ended with the thief seized and imprisoned in Annwn, and another obscure divinity, Amaethon, is said to have stolen three of Arawn's animals — a cluster of motifs suggesting an old belief that domesticated beasts originated with the gods and reached humanity by gift or theft. In more recent Welsh legend his throne slipped from him: the later sources make Gwyn ap Nudd the king of Annwn, and the courteous king of the Mabinogion recedes behind that newer figure.

The paragraphs below are extrapolated; no source supports them.

Arawn reads as a personality organized around measure and compact. He answers an insult not with violence but with a precisely specified restitution; his decisive combat is defined by a single permitted blow; his friendship, once earned, is durable and generous. That suggests a formal, ceremonious temperament — exacting about obligation, comfortable acting through proxies and exchanges rather than in his own person, and more interested in equilibrium between realms than in conquest. The inference leans on the structure of the Mabinogi tale rather than on any stated inner life.
