The Stones of Time - Calendars, Sundials and Stone
Chambers of Ancient Ireland by Martin Brennan. First
published in 1983 as The Stars and the Stones.
Older than the pyramids and predating Stonehenge by
at least a thousand years, the stone complexes of ancient Ireland have been
extensively excavated and studied, yet they have refused to give up their
mystery. Archaeologists have speculated that the chambers were tombs. Art
historians have tried to interpret the enigmatic designs painstakingly carved
into the faces of the stones. But the real function of these ancient structures
can be understood only when the art and architecture are seen to be parts of a
Through a combination of careful observation, analysis of the astronomical
alignment of the sites, and insightful interpretation of the megalithic symbols
and carvings, Martin Brennan argues that the mounds and art are interconnected,
sophisticated calendar devices. At critical times of the year, the rising or
setting sun projects beams of light into the inner chambers of the mounds,
illuminating specific images carved on the stones. Those images seemingly
abstract wheels, spirals, and wavy lines suggest provocative new insights into
their makers' understanding of celestial cycles and the importance of those
cycles in human affairs. Google Books Listing.
Introduction to The Stones of Time
The River Boyne takes a spiral course as it meanders up from the plains of
Kildare, winds its way through Meath and takes a curious bend before emptying
into the Irish Sea. The bend in the river encloses a picturesque area dominated
by three large stone structures known as megalithic mounds and named
Dowth. These are
strategically positioned on ridges, appearing above
a landscape dotted with smaller mounds, earthworks and standing stones.
The Boyne Valley complex continues to be an imposing and impressive feature of
the landscape today, as it was when erected over five thousand years ago during
the age of stone. It belongs to the Neolithic period and its major structures
were completed sometime between 3200 and 3700 BC according to radiocarbon
dating. This places the mounds among the world's oldest remaining buildings.
Another striking feature has only recently become known. One of the mounds in
the complex, Newgrange, was found to be aligned to the position of the rising
sun at winter solstice, the shortest day of the year.
The earliest reports of this event were not taken seriously, but in time the evidence proved
overwhelming - Newgrange was a large-scale solar construct, intentionally
designed and of a type previously unknown.
The recognition that the long passage within the mound at Newgrange admitted a
narrow beam of light illuminating the central chamber at midwinter added an
entirely new dimension to Boyne Valley studies. There was no doubt that the
light made its appearance every year in spectacular fashion, but how could this
discovery be reconciled with conventional archaeological theories regarding the
purpose of the mound? Newgrange was and still is considered to be a giant
tomb, yet the new information tended to support the alternative theory that such
megalithic structures were designed for astronomical purposes.
My own field of research involves yet another intriguing feature of the mounds.
The complex of sites in the Boyne Valley contains, painstakingly engraved in the
chambers and passages and on the kerbstones surrounding the mounds, perhaps the
largest accumulation of Neolithic art in the world. My main long-term project
was, if possible, to explain the meaning and purpose of this vast collection of
enigmatic abstract art. By the end of 1979, after ten years of research, I had
already come to some preliminary conclusions.
The alignment of Newgrange to the midwinter sun was evidently a major feature, central to the concept of the
mound. I also concluded that the art contained in the mound must directly or
indirectly relate to this central feature. If this relationship between the
mound and its art was correct, it would imply that similar mounds containing
similar art would also feature astronomical alignments.
From the very beginning I could not regard Newgrange as a unique solar
construct. Its size and use of complex techniques suggested that there must have
been preliminary models upon which the scheme had been based. I was also aware
that unless comparable Neolithic devices could be found elsewhere, very little
could be determined about the precision with which Newgrange had been laid out,
or whether or not it represented a systematic method of time reckoning.
The line of enquiry I was pursuing could be verified only by systematic field
research embracing all the major mounds in the Boyne Valley. In order to help
eliminate possibilities of coincidence, another large complex of mounds situated
in the Loughcrew Mountains would also have to be investigated. The
complex is second only to that of the Boyne Valley in its size and in the
quantity of megalithic art it contains. Together the two complexes provide the
great majority of all megalithic art in Ireland. Eventually the project would
expand to include most of the Irish sites containing megalithic art.
The mysteries of the art could be explained only in terms of the mysteries of
the mounds themselves, especially the way they interacted with light. The
original art research project was therefore expanded to include an archaeo-astronomical
investigation. Although I had failed to interest archaeologists in my ideas, a
fellow artist and amateur astronomer, Jack Roberts, saw a certain logic in my
reasoning and was keen to test my ideas in the field.
Our field research began in late 1979 at Newgrange, where we observed the
midwinter sunrise, and ended one year later in the chamber of nearby
where the rays of the setting sun projected a beam of light at winter solstice.
During 1980 we had made comparable solar observations at over thirteen
megalithic sites. We gradually came to realize that the mounds were indeed
accurate sun chronometers whose structures are a celebration of light and
measurement. We also discovered a clear and distinct link between megalithic art
and the astronomical events that animate megalithic structures, giving them meaning and function.
The story of our discoveries is the subject of this book. But many researchers
before us had, in varying degrees, anticipated or at least suspected an
astronomical significance, both in the alignments of the mounds and in the signs
and symbols that make up megalithic art: their story should also be told. Even
before these comparatively modern visitors, however, Celtic history and
tradition alike echo the high prestige of the mounds. Locked away in Gaelic
manuscript and lore are fragments of evidence which show that these mounds have
captured the imagination and admiration of generations of peoples, extending
down through ages of time.

The Boyne Valley Vision
by Martin Brennan. First published in 1980 by Dolmen Press.
In The Boyne Valley Vision Martin Brennan
presents an entirely new interpretation of these monuments, one which challenges
the conclusions of earlier studies and offers conclusive evidence which
radically changes our knowledge of megalithic culture in Ireland.
Martin Brennan used a different kerbstone numbering system at Knowth to the George Eogan K1 to K127 system.
He used a system based around North, South, East and West, see comparison table.
Martin Brennan trained in visual communication at Pratt
Institute. He has travelled extensively in Mexico where his interests in
prehistoric rock inscriptions, ritual, and traditional art developed.
Spending more than a decade in Ireland engaged in active research on megalithic art, he
tapped into some of the earliest methods of recording numbers and the
fundamental beginnings of writing, and reported these startling discoveries in
his critically acclaimed 'The Stars and Stones', later reissued as
'The Stones of Time'. He is also the author of
Hidden Maya. He lives and teaches in Boulder, Colorado.
