The eastern oracle hole viewed from the outer northern apse.
This oracle hole is much more crudely
executed when compared to the western example. The hole is not in the centre
of the slab, but is worked into the northern edge. Three sides of the hole are
nicely finished, but the outer side is formed by the addition of a separate
limestone block. The stone has obviously been fairly heavily eroded below that
block and it may be that the original appearance was much neater than what we see today. In common
with the second oracle hole, the sides of this hole taper in towards the top,
the perspective of this photo serves to conceal this feature.
The hole communicates the outer northern apse with the intramural room to the
north of the entrance, there is a large upright
stone behind this slab covering the southern half of its inner surface which may explain the need to position the
hole on the block
edge.
