Recently
reports have surfaced about carvings on stone panels in a Neolithic passage
tomb known as “Cairn L,” on Carbane West, at Loughcrew, outside Oldcastle, in County
Meath, Ireland which supposedly record an eclipse that happened in 3340 BC. I think this is another huge over-reach in interpretation, but you can read below and make up your own minds.
In 2013,
Dr. Frank Prendergast completed a detailed study of the monument and found no
reason to assign any such significance to any of the carvings.

“The chamber and passage are
orientated east-south-east. There are no apparent distinctive topographical or
monumental features on the horizon in this direction. This could suggest an
alternative imperative for the orientation of the tomb. The summary
astronomical investigation presented here was undertaken as part of a national
survey of passage tombs undertaken by the writer. From that, the measured
passage orientation (azimuth or direction relative to true north), the horizon
altitude and the geographical location of Tomb L were used to calculate the indicative
astronomical declination (δ).
From δ, the likely dates of sunrise for the north and south azimuth limits of
the tomb/passage and the central axis were determined. Although the azimuths
were derived from compass bearings, above data are sufficiently accurate to
allow for a determination of the dates and date ranges of solar illumination
within the tomb to an accuracy of a few days. These should be consistent with
what would be seen by an observer located in the chamber.”
(Prendergast 2013)
“In assessing the significance and meaning of
tomb orientation, numerous criteria/factors (including astronomical) can
explain any possible intentionality and, thus, deliberate axial alignment.
There is also the possibility that tomb orientation can be random. In the case
of Tomb L, and in the apparent absence of any indicative/distinctive natural or
built horizon feature that might have acted as a focal target, the tomb may
have been simply built to face the rising sun.” (Prendergast
2013) Notice Prendergast’s conclusion that the tomb was built to face the
rising sun, but not aligned with any specific landscape features.
“These
phenomena are interpreted by the writer as not having had any calendrical
significance in the prehistoric past and popular ideas of Tomb L being aligned
towards the mid-quarter dates of November 5/February 4 are thus challenged here
for several reasons. Although sunlight will penetrate to the edge of cell 6
around these dates, any claim for the alignment of the passage axis being
calendrically significant in an early prehistoric context has little basis in
fact. Tomb L was built in the Neolithic and, as such, predates (by almost three
millennia) any late Iron Age/early Medieval evidence for calendrical
subdivision of the solar year.” (Prendergast 2013) Prendergast found no significant
archeoastronomical orientations at Tomb L. He also made no mention of any of
the stone carving supposedly portraying an eclipse. Prendergast’s conclusion is
that this tomb, and thus its carvings, have no celendrical significance.
Brennan (1983) conducted an extensive study of Irish Burial Mounds, including
Tomb L, and found numerous carved images that he identified as lunar images.

But then,
the theory popped up that the carved boulder at the end of the passage in Tomb
L portrays the earliest known record lf a solar eclipse. “Our ancient Irish
ancestors carved images of an ancient eclipse into giant stones
over 5,000 years ago, on November 30, 3340 BC to be exact. This is the oldest
known recorded solar eclipse in history.” (Hayes) I believe that this extraordinary claim can be first attributed
to Dr. Philip J. Stooke,
Philip J. (1994) who stated “The
historian Diodorus Siculus (writing shortly before the time of Christ but
quoting Hecataeus, some five centuries earlier, 'and certain others') wrote of
the 'Island of the Hyperboreans' ... ‘there is also on the island both a
magnificent sacred precinct of Apollo and a notable temple which is adorned
with many votive offerings and is spherical in shape... They say also that the
moon, as viewed from this island, appears to be but a little distance from the
Earth and to have upon it prominences, like those of the Earth, which are
visible to the eye. The account is also given that the god visits the island
every nineteen years....’ The nineteen year period is presumably that between
almost identical eclipses.” (Stooke 1994)

Extraordinary claims require extraordinary evidence, and I have been
unable to find any explanation of this claim except Stooke’s reference to
Diodorus Siculus who had never, of course, visited Ireland. Another citation sends us to “Irish archaeo-astronomer Paul Griffin has
announced the confirmation of the world's oldest known solar eclipse recorded
in stone, substantially older than the recordings made in 2800 BC by Chinese
astronomers. This finding was made at the world's oldest lunar eclipse tracking
multi cairn site at the Loughcrew Cairn L Megalithic Monument in Ireland, and
corresponds to a solar eclipse which occurred on November 30, 3340 BC,
calculated with The Digital Universe astronomy software.” (Colomba 2020)
Now I do not doubt that there was an eclipse then if astronomers agree on it, I
just doubt that these petroglyphs have anything to do with it.
I have
written a few times on RockArtBlog about eclipses (check the cloud index at the
bottom). The thing that is really unique and impressive about a solar eclipse
is that most partial eclipses would have been missed, the sun is partially
eclipsed but it is still too bright to look directly at so all the viewer would
notice is the world around him is not as bright for a while. A total solar
eclipse, on the other hand, is a tremendously impressive with its blackout and
the ring of fire. It is my belief that the ring of fire, by far the most
impressive part of a solar eclipse, is what would be shown by someone recording
the event. To see a record of a total solar eclipse I would expect to find an
empty circle with no internal details, but externally some rays or markings
could represent the solar coronal glow and discharge. These markings at Cairn L
just don’t look right to me to be a record of a total solar eclipse. And I have
been unable to find any explanation of that claim. Now concentric circles just
might represent a sun, but not one being eclipsed.

But
this is not the most extreme claim made for the astronomical symbolism at Cairn
‘L.’ ”Just
on the left, as you enter the chamber, is a lovely little design of nested
arcs, some 13 in all, radiating out and down from what seems to be a rising
heavenly body. Close by is another smaller set of nested arcs. Martin Brennan
has suggested that this image may represent an image of a transit of Venus.” (Fr. O’Flanagan History Center) Now
we are supposed to accept that 5,355 years ago ancient Irish astronomers made
naked eye observations of a transit of the planet Venus in front of the sun’s
disk? To believe that they could see that is even more preposterous than the
eclipse claims. The first transit of Venus recorded in history was on 4
December 1639 by English astronomer Jeremiah Horrocks (Naeye 2012) so I have to
be skeptical about the Cairn ‘L’ claim to that as well. All in all these claims
appear to be a whole load of fantasy with apparently no proof to back them up.
NOTE 1: I contacted the Fr. O’Flanagan
History Center asking for clarification and information but I have received no
reply. I have also failed to find Irish Archaeo-astronomer Paul Griffin’s paper that
apparently leads to the conclusion involving the portrayal of an eclipse. My
search for that paper online leads to a dead end every time. My negative
conclusions are based on a lack of confirming data.
