Maeshowe – part two
The dark winter round.
Here the masons built a hive
That the dead lords and ladies
Might eat always honey of oblivion.
Here masons and starwatchers
Conspired: in midwinter
The good star, the sun, would awaken the sleepers.”
By Sigurd Towrie

Based on shared architectural elements, Maeshowe has given its name to a specific class of chambered cairn.
Characterised by side cells branching off from a central chamber accessed by a long, low passage, the Maeshowe-type cairns have been linked to relationships further afield, specifically Ireland.
Irish passage grave architecture, it is suggested, was just one element copied by “ambitious and widely travelled” Orcadian groups looking to “enhance their power by appropriating an exotic tradition”. 
But despite the similarities, Maeshowe has distinct differences and, it could be argued, may have had a different role. As we have seen, it contained little, if any, human remains and it has been argued that access to its interior was never intended.
Maeshowe perhaps represented something else entirely. Does this anomalous nature hint that it was later in the history of chambered cairns?
An earlier building
Maeshowe was built on an artificial platform fashioned by depositing huge quantities of clay on a natural knoll to create a level surface.
In 1991, excavation outside the entrance revealed a stone drain beneath the clay platform. Soil analysis suggested occupation deposits, so the drain was interpreted as the remnants of an earlier Neolithic house. 
This building, it was suggested, had been demolished and the area covered with clay to allow the construction of Maeshowe – on the same alignment as its predecessor.
To the excavators, the location chosen for Maeshowe was clearly influenced by the earlier building:
Because we have no dating evidence for Maeshowe, how its suggested predecessor fits into the timeline of Neolithic Orkney remains unknown. But as we will see below, the construction of a Maeshowe-type cairn on top of earlier buildings has been encountered elsewhere.
The 1991 investigations also revealed a large standing stone socket hole on the platform to the rear of Maeshowe. Based on its depth, the megalith it once contained was bigger and taller than those found at the nearby Stones of Stenness. 
It had been carefully removed in antiquity but on the available evidence we do not know when. Nor do we know how it related to Maeshowe.
There, excavation between 1978 and 1982 showed that an equally large standing stone stood beside a Neolithic structure that was replaced by a building interpreted as a stalled cairn. 
This interpretation is problematic, however, considering the presence of a hearth – a feature highly unlikely to be found within a funerary structure. Instead, architectural parallels between Structure Twenty-Seven at the Ness of Brodgar and the Howe “stalled cairn” suggests it served a different, and as yet unclear, role.
Whatever this role was, the Howe structure was very carefully dismantled and covered in a thick layer of clay. On top of this a Maeshowe-type passage grave was built, on the same alignment as its predecessor:
How the standing stone related to the Maeshowe-type cairn at Howe is not clear.
All that can really be said is that it was removed at some point before the Early Iron Age re-occupation and remodelling of the site. The excavators thought it may have been removed prior to the construction of the Howe cairn and ditch.
The fact the stone socket cut the surrounding ditch, however, has been taken as evidence the Maeshowe-type structure and the megalith were contemporary. 
If the standing stone was earlier than Maeshowe and part of a stone circle, it may be that more sockets lie beneath the clay platform on which the passage grave was built.
Were the megaliths incorporated into Maeshowe once part of this ring of stones? Until proof is found – which is unlikely given Maeshowe’s protected status – the existence of an earlier stone circle must remain hypothetical.
The dark of winter
With its south-westerly facing entrance, Maeshowe’s best known attribute is its orientation towards the setting sun around midwinter.
But although the idea of the last rays of the winter solstice setting sun piercing the darkness of the cairn’s interior conjures suitably dramatic imagery the actual situation is much more complex.
As archaeoastronomer Clive Ruggles pointed out:
Although this seems pretty clear cut, note that the orientation refers specifically to the inner passage. And therein lies the problem. Much of what has been written about Maeshowe and the winter solstice relates to the current configuration of the entrance and outer passage.
Not only was the outer arrangement reconstructed at some point after the excavation but details of the original layout are lacking. Not only was it probably ruinous but further damaged by Farrer’s operation to clear it out.
As Petrie pointed out in 1861, the outer passage appeared to have originally 71cm (28in) high  – lower than the intact inner section.
Although unroofed when excavated, if the outer section was originally covered then this would dramatically impact the sunlight entering the chamber .
There is, however, no reliable evidence that the outer passage was covered.The situation is not helped by inconsistencies in the early accounts and plans.
As mentioned previously, in his 1861 letter to the local newspaper, Petrie said “the covering stones had been removed for about 22½ feet” . A very brief report to the Archaeological Journal, also written in July 1861, states: “the covering stones for about 15ft were wanting” .
Knowing Petrie’s work elsewhere, I find it hard to believe he would not have spotted and recorded collapsed roof material.
It has been suggested that the outer section “may have been in the form of an open trench” leading to the actual entrance – much as the reconsolidated entrance appears today . It is interesting to note that the excavators of the Maeshowe-inspired passage grave at Howe suggested a forecourt enhanced the grandeur of that construction .
If it was the blocking stone that marked the original entrance to Maeshowe, via the megalith-lined inner passage, and was used to seal the chamber, it did not completely block the passage. The top is lower than the passage roof so, when in place, left a distinct gap. It is often suggested this gap acted as a “lightbox”, similar to the one found in Newgrange, Ireland. However, once again, given the uncertainty surrounding the original entrance, this function cannot be verified.
Because the form of Maeshowe’s outer passage is not clear, we cannot say how the midwinter sunsets affected Maeshowe and how, if at all, they were experienced in the central chamber. But whether the sunlight penetrated the depths of the chamber or the setting sun was framed by the entrance, the time around the winter solstice was clearly significant.
It may be then, as now, it marked the passing of time – the death of the old year and the birth of the new one. In the dark depths of an Orkney winter today, the solstice remains a welcome indicator that the sun is returning.
To the people of Neolithic Orkney the return of the sun heralded a resurgence of light and the return of life to the land – just as it still does.
Although in Orkney the worst of winter often follows the solstice, it remains a comforting thought to know the days are lengthening again.
