The Four Branches of Y Mabinogi

The Four Branches of Y Mabinogi — Pwyll, Branwen, Manawydan, Math — survive in two fourteenth-century manuscripts but were composed earlier, from far older tradition. Arthur never appears in them. They are read here because they are the finest sustained expression of the mythological grammar the Arthurian tradition inherits: kingship held on moral conditions; the land's fertility bound to the ruler's conduct; the Otherworld as a courteous, dangerous neighbor; and the great vessel — Brân's Pair Dadeni, the Cauldron of Rebirth, which restores dead warriors to life but leaves them mute.

Read the First Branch watching Pwyll's year in Annwfn: he exchanges shapes with its king, keeps faith with the king's wife, and returns having earned the title Pen Annwfn, Head of the Otherworld — sovereignty won by restraint rather than force. Read the Second Branch watching the cauldron and the wasting of two islands over an insult to a woman; read the Third watching Dyfed fall silent under enchantment, an emptied land waiting for right action to restore it — as close to the romance Waste Land as anything in Celtic literature. Read the Fourth watching what happens when kingship, magic, and desire are all misused at once.

The scholarly caution is part of the unit: the Four Branches are literature, not a mythological handbook, and their author (some argue a single, subtle redactor) has purposes of his own. Use Sioned Davies's translation and notes; read Guest's Victorian version afterward if you want to see how the nineteenth century received it — that reception is itself part of Movement VI's story.
