The following 10 motifs are defined (M.J. O'Kelly and C. O'Kelly [1983,
Subdivided in curvilinear (circles, spirals, arcs, serpentiforms,
and radials) and rectilinear (zigzag, lozenges/triangles, offsets
- offsets and
- parallel lines.
Cupmarks are not a motif in the above scheme, because it was
to distinguish between natural hollows and man made ones.
A complete corpus of known megalithic art is provided for Newgrange

and C. O'Kelly ). Cup marks are
Almost no pick dressing has taken place at Dowth, while at Newgrange
every orthostats is pick dressed.
The quality of the technique or artistry of the megalithic art at
is lower than at Newgrange or Knowth.
It is possible to distinguish Newgrange, Knowth and Dowth by the use
of motifs. E.g. Newgrange has relatively much more
dot-in-circles and zigzags than Dowth.
In Newgrange lozenge and zigzags are the commonest, then circles,
radials (but they are in inconspicuous places), than spirals. The
motifs at Newgrange are radials, parallel lines and offsets.
The alignment of Newgrange is given towards winter solstice. The
north direction in the general plan of Newgrange (page 15) is
wrong. Below is a better alignment of the True north:
on the direction of the roofbox can be found at this
The alignments measured by O'Kelly at Dowth
are: Dowth North 250°
and Dowth South: 234°. New measurements have been taken with a
magnetic compasss [Prendergast and Ray, 2002].
See for evaluation of these values my Dowth
Cut-through of the passage
It looks that the cut through of the passage on page 88 is not
correct. The heights are ok, but the incline of the passage is not
correct (wonder how this was achieved;-). Page 94 and 108 look to
... that the symbolical meaning was the original
for Irish passage-grave art, beginning with the random carving
which had a meaning for those who applied them, or caused them
and that it was only with the passage of time, as the tomb
more expert and sophisticated generally, that the aesthetic
the carvings began to emerge and develop and designs and
to be achieved, though perhaps this aspect never entirely
symbolism, latent or otherwise (O' Kelly ,
