THE IRISH UNIVERSE 

While the diagram on page 293 is intended to be a symbol of the cosmos, its two cardinal points, A and L, are situated in Ireland, as shown in Figure following. The more important of these points, the ' prisme O' (287.10), is identical with the omphalos of 111.3, Shaun's navel in the centre of Ireland. This point is defined as ' the Great Ulm (with Mearingstone in Fore ground)' (293.14; that is, 'the Great Elm with the Mooring-stone in the foreground'). That the centre of Ireland and the Stone of Divisions are intended is clear from the sentence which follows: 'Given now ann linch you take enn all'. The words 'enn all' include an allusion to Lough Ennell, which is just south of Mullingar in Central Ireland, and only a few miles from the Stone of Divisions. Point L is reached when a horizontal 'copyngink strayedine' (294.02) is drawn east from Point A, until it reaches ' Lambday', or Lambay Island, which is three miles off shore, just north of Dublin and on precisely the same latitude as Lough Ennell. Clearly the first, wholly Irish, circle is Shaun's, while the other, half in Ireland and half outside it, is Shem's.
