Overview

The historic name for the fertile plain of the Finn and Foyle around Raphoe and Lifford. Medieval tradition explains the name through Íth, a figure of the Lebor Gabála Érenn; archaeologically, it is a lowland rich in prehistoric monuments, including Beltany stone circle.

Magh nÍtha — the plain of Íth — appears in medieval Irish literature as one of the named plains of the north. The name survives as a regional identity rather than an administrative unit, which makes its edges difficult to define precisely.[1]

Beyond the Bend uses Magh nÍtha as a landscape frame for monuments in the Raphoe lowlands. Membership of this landscape is an interpretive grouping and is shown as such.

The historic extent of Magh nÍtha is not precisely known; no boundary is drawn.

Modern interpretation

The story is an origin legend for a placename. It shows that the plain was a named and significant territory to medieval writers.

Reliability

Pseudo-historical narrative. Not evidence for a historical person named Íth.

Research questions

  1. How did the extent of Magh nÍtha as a named territory change between the early medieval period and the present?
  2. Do the prehistoric monuments of the plain show any consistent relationship to the rivers Finn and Deele?
