Pronunciation

How Nisien was spoken

/ˈnɪsɪɛn/ Modern Welsh
Ni- Voiced alveolar nasal [n] plus short close [ɪ], the light unstressed opening; Welsh i is close and short, never the English diphthong of 'nine'.
-si- Voiceless alveolar sibilant [s] and short [ɪ] again — the stressed penult, where Welsh accent always falls; a clean hiss, never voiced to z.
-en Short open [ɛ] and final alveolar nasal [n]; the last syllable falls away unstressed, as in Welsh pen 'head'.

Peace, Brother of Efnysien

The Gentle Twin of the Second Branch

Nisien is one half of the strangest doublet in the Mabinogi: twin brothers, sons of Euroswydd, whom the Second Branch introduces with a single matched sentence — Nisien, the good man who would make peace between two armies when they were most furious; Efnysien, who would set two loving brothers fighting to the death. The tale then gives the whole war to the cruel twin and keeps the gentle one as its standing might-have-been: peace personified, present at the court that marches to Ireland, and never once allowed to prevail.

The Peace Between Hosts

The tale's whole dossier in one clause: he would bring two armies to peace at the very height of their rage.

The Twin

Son of Euroswydd and Penarddun, twin of Efnysien — the gentle half of a pair the tradition built as peace and strife in one cradle.

Euroswydd's Line

Half-brother to Brân the Blessed, Branwen, and Manawydan — kin to the children of Llŷr by his mother's side.

The Road Not Taken

Wherever the Second Branch's counsel is weighed, Nisien is the standing alternative: the peace that was in the house and was not chosen.

Mythology

Stories of Nisien

Nisien has the smallest dossier in the Mabinogi and the clearest definition: he exists as one half of an antithesis. The Second Branch of the Mabinogi, Branwen ferch Llŷr, names him exactly once as a character and then spends its whole length on the war his brother kindles. What survives of him is a sentence, a lineage, and a presence — and the Welsh tradition built an entire moral pole out of that spareness.

Branwen ferch Llŷr

The Two Sons of Euroswydd

The Second Branch introduces the twins in a single balanced construction, the most quoted sentence either brother ever gets. Nisien, the tale says, was a good man: he would bring about peace between two armies when they were at the height of their fury. Efnysien would bring about a quarrel between two brothers when they loved each other most. They are twins, sons of Euroswydd by Penarddun — and so half-brothers to Brân the Blessed, Branwen, and Manawydan, Penarddun's children by Llŷr.

The construction is the whole point: Welsh prose has no other pair like it. The tradition does not describe two temperaments; it defines two forces — peace and strife — as brothers born in one hour, and then sets them loose in the same household. Every reader of the branch knows, before the horses are harmed, exactly which twin will act and which will stand by.

Branwen ferch Llŷr

The Horses at Aberffraw

When Brân consents to give Branwen in marriage to Matholwch, king of Ireland, and the wedding is held at Aberffraw, it is Efnysien — insulted that the match was made without his leave — who takes revenge on the groom's horses: he cuts off their lips to the teeth, their ears to their heads, their tails to their backs, and the eyelids to the bone. The outrage becomes the war's first cause, patched over with reparation and the gift of the Cauldron of Rebirth, and reopened in Ireland when Branwen is made a scullion and struck daily in the kitchen.

Nisien's place in all this is the tale's deliberate emptiness: the peace-maker is there, kin to all parties, gifted by his own description with the one power the crisis needs — and the text never once shows him using it. The mutilation stands unappeased from its author; no embassy of Nisien's is ever recorded. The Second Branch's tragedy is written so that the reader supplies the missing twin.

Branwen ferch Llŷr

The War Over the Sea

Brân wades the sea at the head of the hosts of Britain, for no ship can carry him, and the war that follows destroys both kingdoms. The Irish revive their slain in the Cauldron of Rebirth, so that they rise to fight again, and the balance breaks only when Efnysien — feigning death among the corpses, flung living into the cauldron — stretches himself out and bursts it, dying in the act: the strife-twin consuming himself to undo the one weapon his own first outrage helped set in motion. Of the men of Britain only seven come home; Branwen dies of a broken heart on the shore of the Alaw.

Nisien's name is not among the dead, the seven, or the counsellors: the tale simply stops mentioning him. Scholars have long read the silence as the branch's own verdict — Mac Cana and MacKillop alike treat the twins as a personified antithesis, peace and discord hypostatized as brothers, and on that reading Nisien's function is complete the moment the paired sentence is spoken. He is not a character the tale forgot; he is the peace the tale declined.

Scholarly Reading

The Antithesis Made Flesh

The modern handbooks are unusually agreed about what the twins are. Mac Cana reads the pair as the Mabinogi's clearest case of abstract forces embodied as kin: the redactor names Nisien and Efnysien in one breath because they are one idea in two bodies. MacKillop's dictionary keeps both entries short for the same reason — there is no cycle, no second tale, no folklore of Nisien to collect; the dossier is the Second Branch and nothing else. Koch's encyclopedia files both under Branwen ferch Llŷr.

The names themselves resist resolution. The traditional glosses — 'peaceful one' for Nisien, 'double enemy' for Efnysien — are older scholarly convention rather than settled etymology, and the Geiriadur Prifysgol Cymru and the handbooks record the derivations as uncertain. What is certain is the structure: two names, two clauses, one cradle. The Welsh tradition made its peace-maker the way myth usually makes its gods — by naming the opposite and letting the pair do the work.

Extended Lore

Nisien is the proof that a figure can be made of almost nothing and still be one of the most exact things in his tradition. One sentence, one lineage, no deeds — and from that the Second Branch draws a whole theology of peace: that it exists, that it lives in the same house as strife, that it can be kin to the war-makers and married into every court, and that a host can carry it over the sea and never once take it out. The tragedy of Branwen is often told as Efnysien's story, but it is just as much Nisien's: the war happens in the presence of the one man whose nature is to end it, and the text makes sure we notice by telling us his nature first and his absence always.
