Act I — Deep Ireland

Deep Ireland
Ten millennia of human presence on the Moy valley, from the first hunters arriving behind the retreating ice to the Iron Age warrior aristocracy that would produce Fiachra. Rome never crossed the Irish Sea; our ancestors remained free, and outside writing.
After the Ice
First footprints on the Moy
Hunter-gatherers reach the Atlantic coast as the ice retreats. The Moy estuary — salmon-rich, sheltered by Killala Bay — is one of the places they stop. Seasonal fishing camps leave the first traces of continuous human presence on the land that will one day be called Tireragh.

Farming arrives from Anatolia
A migration wave carries wheat, cattle, and stone-building techniques from the Aegean across Europe. The same people who build the Irish tombs will, a thousand years later, begin Stonehenge.

At Carrowmore near Sligo, Neolithic farmers build one of Europe's oldest megalithic cemeteries. Listoghil, its central cairn, is dated c. 3500 BCE. The monuments look out over the same bay the O'Dubhda will later defend.

On the north Mayo coast, a community clears forest and lays stone walls around small fields. Buried under blanket bog for five thousand years, these are the earliest known field systems anywhere on earth.

Fifteen passage tombs rise on the Bricklieve ridge above Lough Arrow, linked by the Unshin river down to Carrowmore. The landscape the O'Dubhda will inherit is already mapped by the dead.

Bronze comes to the Moy
Copper from Kerry and tin traded from Cornwall reach the west of Ireland. Ringforts and field boundaries from this era still fossilise the shape of later townlands across Tireragh and Tirawley.

Irish gold reaches Scandinavia
Bronze Age trade routes carry Irish gold torcs as far as Denmark. Ireland is on the map — unreachable by land, but plugged into a maritime world that runs from the Baltic to Iberia.

La Tène — the Celtic world
Art styles, weapons, and a warrior aristocracy spread from central Europe westwards. Ireland absorbs the culture without the migration. The warrior-aristocracy that will produce Fiachra is taking shape.

Caesar conquers Gaul
Roman legions subdue the Gauls. Britain will follow a century later. Ireland — Hibernia to the Romans — is beyond the horizon and stays that way.

Agricola looks across the sea
The Roman governor Agricola, standing on the Scottish coast, reckons one legion would suffice to take Ireland. Rome never crosses. Our ancestors remain free — and outside writing.
Tacitus, Agricola c.24The royal mound at Cruachan
Rathcroghan in Roscommon becomes the ceremonial capital of the Connachta. The mound where Dathi, three centuries later, will be buried under a red pillar stone.

The name does not yet exist, but the territory is set: the Moy valley, the baronies later called Tireragh, Tirawley, Erris. The stage is ready; the family is one generation away.
