The Lunar Wobble

The Apprentice Pillar, 15thC Rosslyn Chapel, see below

FOGS JUNE 2004 solstice newsletter started the alert for all this wobble-watching. Now, two months after the wobble — lunar maximum occurred Sunday, June 11, 2006 when the moon reached its major standstill — we on the 57th degree parallel are experiencing withdrawal from our companion in orbit.

Orkney, Shetland and Lapland watchers are even more deprived, as the earth’s satellite barely shows her face at full above the southern horizon. This, its wildest fluctuation in the 18.6-year Metonic cycle, will continue into the autumn months. However by winter solstice we shall once again have a companion in full visibility in the night skies.

Think of it this way: in the darkest days of December, the sun at our latitude rises in the south-east and sets in the south-south-west, barely grazing the tops of some of our frostly hills.

This summer, the full moon has been doing just that: rising qnd setting (on full moon night and a couple of nights on either side) in roughly those same compass points, reflecting in amazing precision the path of our solar partner.

That is a simplification. It means if we aren’t looking in the right place, chances are we’ll miss it. It is more precise to say that on October 22, 2005, the moon was closest to full (71%) while standing at its most northerly position in our skies for 18.6 years.


By definition, quarter moons stand at the most northerly point in the sky.

For an exact calculation, check Victor Reijs and our FOGS moon standstill posting, immediately below. There is a discussion group at Archaeocosmology.

Many archaeoastronomers believe that some cupmarks on NE Scots recumbent stone circles mark the maximum moonset for this cycle. If so, then the circle-builders’ technology predated Meton (432BC) by some 3000 years.

Those of us planning to attend FOGS’ 2006 AGM at Cothiemuir on September 16th will be able to check for ourselves as the large recumbent there displqys a cluster of cupmarks on its face with a view angled farthest to the SSW — the most extreme viewing position possible from within the circle. Cothiemuir, NJ617 198, is accessed from My Lord’s Throat, and is one of the earliest of the NE’s RSCs. Contemporary neighboring Old Keig has the largest recorded recumbent stone, weighing in at 53 tons.

Message in a Bottle: Crichie Past

Beaker grave cremation pot and horn spoon found in 1855 by Dalrymple at Port Elphinstone henge, 'Druidsfield', Broomend of Crichie

During last summer’s excavation by Dr Richard Bradley’s team from Reading University at Druidsfield, Crichie, Port Elphinstone, Inverurie, a communication from the past was unearthed. The henge itself left a few clues to its use as a sacred processional terminus during the Bronze Age (one-mile-long stone avenue between Kintore and Crichie), but the message-in-a-bottle was far more precise in date. It was found standing upright in a spoil heap left by a previous archaeologist, and contained small fragments of window glass wrapped in a sheet of the Penny Free Press & Northern Advertiser

The glass was inscribed with the names of antiqurian Charles Elphinstone Dalrymple, his two colleagues and the local farmer of Broomend, with the date of their excavation, November 22, 1855. Victorian antiquarians frequently left small tokens for their successors to find.

Dalrymple’s family owned Logie, near Pitcaple; sometimes called Logie-Elphinstone. The Port Elphinstone excavation was one of his favourites and showed most detail: including the avenue of 72 megaliths stretching between Crichie and Tavelty, Kintore. Only two of these avenue stones remain.

Another feature now lost to the Reading team which Dalrymple was fortunate to find and record was a triple-ring circle a few metres north of the Druidsfield henge — now forming basement and foundations of a Port Elphinstone housing development. It is hoped the Reading team’s interest in the Kintore corridor will help protect it from further blanket development. The corridor sadly runs parallel with the A96 dual carriageway between Thainstone Mart and the Kintore Industrial Estate. ©MCN

Aberdeen Pictish Conference

Pictish eagle fragment found on Tullo Hill at Forgue-- DES 1999:9 first Pictish eagle-stone to be discovered in the 'Kingdom'

University of Aberdeen’s Research Institute for Irish and Scots Studies will host a conference entitled Fresh Pict: Problems Revisited at King’s College on Saturday, November 28th, 2006. At that time papers previously addressed to the prestigious Leeds International Medieval Conference will be given. The list of speakers is impressive:

Lloyd Laing, Simon Taylor, David Dumville, Gordon Noble, Nicolas Evans, Strat Halliday, Andrew Heald and Mike King. It is refreshing to see work continuing in the NE where Pictish fragments continue to be found, viz. Forgue eagle-stone, left (DES 1999:9) and a ‘creature’ found in a garden wall at Rothiemay (DES 2002:11). More information available from the Institute, Kings College, University of Aberdeen.
DES = Discovery and Excavation Scotland, whose online documentation of earlier DES publications has reached 2008.

daVinci Sparks Interest in Rosslyn
Rosslyn Chapel, south of Edinburgh, has traditionally attracted the specialist visitor interested in its alleged connection with the Knights Templar and the Holy Grail. Following the release of Dan Brown’s ‘daVinci Code’, visitor numbers have tripled.

Rosslyn's 15thC barrel-vaulted ceiling divided into five compartments. The crypt has Templar carvings.

The Rosslyn Chapel Trust chose a timely moment to make a record of what is probably a unique example of late-Medieval ecclesiastical architecture of the pre-Reformation period.

The chapel was begun in 1446 at around the same time as work started on Glasgow Cathedral. It is one of the few remaining intact pre-Reformation chapels left in Scotland. It towers over the edge of Rosslyn Glen, whose layers of sand, gravel and clay have posed subsidence problems in the past. One exit from the crypt opens on to a gravel bed.

AOC Archaeology Scotland have been employed to create a laser scan record of both interior and exterior; they hope to avoid pitfalls encountered in photography, where a substantial exterior scaffolding canopy –needed for the work– masked several unique features. Scanning has resulted in remarkable three-dimensional and 2D images of the building and its extravagant architectural idiom. This includes the lavishly-decorated interior with its now-famous ‘apprentice pillar’. It is the first full high-precision record to be made on the site and will prove invaluable for research, conservation and for future generations to refer to as a baseline for the building as it now stands.

It is hoped many of the scanned images will be made available on the web.

Friends of Grampian Stones Spring Equinox 1999 newsletter ‘X’-2

Spring Newsletter 1999 – Vernal Equinox Volume X number 2 (vol.X no 1 was Samhain 98 q.v.)

Picts, Kings, Saints, Chronicles

Pictish carved stone in Inverurie 'Castleyards' old kirkyard

Crescent and V-rod, sun-disk and serpent carved Pictish stone

A pictish one-day conference arranged in honour of Dr Marjorie O. Anderson on the occasion of her 90th birthday was held in the Quad lower college hall at the University of St Andrews on February 13th 1999. A collaboration by the School of History, Early Medieval Research Group, Scottish Studies Institute and Committee for Dark-Age Studies, its focus and its speakers ensured its success. It was fully booked. While Dr Anderson was unable to hear presentations because of illness, she would have marvelled at the excitement and energy generated in both lecture hall and lunchroom by speakers and delegates all pressing to share new developments in this emergent discipline. Drs Simon Taylor and Dauvit Broun unveiled new discoveries in placename survival and the St Andrews foundation legend (versions A and B); Profs. Richard Sharpe and Máire Herbert gave both insular and Irish slants on the political structure of Dál Riata; Isabel Henderson unveiled her theory on specific sculpture schools of the Picts; while both Prof. David Dumville and Dr David Howlett, of Universities of Cambridge and Oxford respectively, kept delegates on tenterhooks with their expositions on the Chronicle of Kings of Alba and on the sacred numerology of its 12thC verse equivalent, the anonymous De Situ Albanie.  Prof. Archie Duncan pulled the audience into the present millennium with his fine elucidation of the Melrose and Holyrood Pictish Chronicles, followed by an immaculate summation and tribute to Mrs Anderson by Prof.Geoffrey Barrow of the University of Edinburgh. He concluded, along with the authors of ‘1066 and All That’ that [the conference, sources and] chronicles were ‘a damn good thing.’  He (along with us) awaits somewhat impatiently the publication of ‘all these riches’.  Members who would like to be advised either of further conferences or publications produced by Dr Barbara Crawford’s Committee for Dark-Age Studies or of details of membership in Dr Simon Taylor’s Scottish Placename Society can write to St Andrews Scottish Studies Institute, University of St Andrews, Fife KY16 9AL. Details of Scottish Placename Society’s webpage are given here.                                             ©1999MCY

WHITECROSS Equinox

ABERDEEN member Dr Theodore Allan remarks on  the Hill of Whitecross one mile south of Chapel of Garioch at NJ 717 225, visible from the recumbent circle of Balquhain but not from Easter Aquhorthies. His interest is apt at this time of year, as it is a marker hill for sunset on the Feast Day of  Bride (Candlemas, and incidentally at its opposite season, Martinmas). However its derivation as the Hill of the White Cross or Crossing may stem from its sacred point of the moon’s crossing or setting – as seen from Balquhain – at the end of summer, the pagan White season, and the point where the full moon sets once in 19 years at its minor standstill. This should be a hill to watch in the summer of 2014 at the next standstill! The physical crossing of the hill must also have had significance to Bronze Age and Pictish descendants, as anyone who has walked the Netherton of Balquhain road can testify.  Leaving behind in the east the Bronze Age burial cairn on Dilly Hill, NJ 751 224, and walking due west, not only does the outline of the Hill of Whitecross draw the eye but for a mile and a half the traveller’s visiion is filled with the sacred shape of the Mother mountain Bennachie. At Burnside of Balquhain, NJ 730 225, where the road turns sharply north, the walker can clearly see how the old road used to rise directly west to Whitecross, itself topped by a cairn. An added delight for placename enthusiasts is the name of this miniscule valley created by the burn which springs on Whitecross’ lower slopes, flows past Burnside and Mains of Balquhain, turning to join the Urie at Drimmies (which Pictophiles will know has its own symbol stone:  it is the Strathnaterick, valley of the serpent of ancient wisdom. This lonely stretch of road, now mostly used by farm traffic, is an inspiration to walk on a spring evening. Thanks to Dr Allan for his observations.

BLUE MOON

TWO OF our regulars communicate on the phenomenon of this year’s blue moons, first in January and now in March; Griselda Macgregor in Inverurie and Trevor Alcott in Crimond are both interested in lunar activity, although from slightly different angles: Ms Macgregor requests the reason for the use of the term ‘Blue Moon’, i.e. for two full moons in the month, while Mr. Alcott likes to extrapolate grander figures of moons in the Metonic cycle.  We might cover both in a limited way.  First, we find  no-one in any context outside Scotland, and perhaps even outside the  bounds of Aberdeenshire, using the term ‘blue moon’ to mean two full moons in the month [in 1999, January 2: 0250; 31:1607, accompanied by a visible penumbal lunar eclipse at 1619; March 2: 0659; 31: 2249 – all times GMT]. The fact that February this year had no full moon at all is purely a figment of modern man’s calculations, as our forefathers when they spoke of the moon, meant the month, and vice versa.  The arbitrary nature of the ‘phenomenon’ can  be seen, particulary in the second March date, to occur only from Europe west, and not for instance, in Australia, where the second full moon falls within April. While not answering the question, we open the door to any contributions from members who have NE knowledge of folkloric or traditional useage.

LUNAR STANDSTILLS

We have touched on standstill moons before, as the time once every  18.61 years that the moon is seen at its most erratic in the night sky, behaving as if with a ‘wobble’. We receive several calls a year requesting more detail for stone-watchers with astronomical leanings – the latest from a member in Edinburgh who prefers anonymity.

Trevor Alcott puts it simply:

‘Correction for our latitude (57ºN approx) is, according to Reed’s Nautical Almanac, seven minutes. The rule is, when declination is north, subtract from moonrise time and add to moonset time. Reverse applies if declination is south. Our biggest problem is one with which mariners do not have to cope, i.e. the height and distance of the horizon relative to the observer, but I promise, you don’t want to know!  The easiest way is to observe a few full moons, note the times, and correct from the nautical times for that particular observation point.’ 

Sensible man.  So, for those early birds preparing for their next maximum and minimum moonset and moonrise, when the moon’s motion relative to other months  is distinctly wobbly,  may we suggest marking your diary now: 

Next major standstill at the full moon nearest to winter solstice occurs in 2005, when the full moon will rise in midwinter at the most northerly point it ever rises.

Next minor standstill, or full moon nearest to summer solstice, happens in 2014.

If we are spared, we may try for a gathering for wobble watchers at a stone circle to compare notes.
