IRISH
SWEATHOUSES
AND THE GREAT FORGETTING
Anthony Weir

Are
Irish sweathouses a continuation of a prehistoric tradition of
inhaling consciousness-altering smoke, recently overlaid with
the prophylactic function of saunas ?
Cannabis is not likely to have
been used in Ireland for a millennium at least, but a much more
seriously-numinous means of widening the awareness is still to
be found all over the island: Psilocybe semilanceata, or
"magic mushrooms"....

Killadiskert, county Leitrim
Irish Sweathouses are small, rare, beehive-shaped, corbelled structures
of field-stones, rarely more than 2 metres in external height
and diameter, with very small "creep" entrances which
may have been blocked by clothing, or by temporary doors of peat-turves,
or whatever came to hand. Most of those which survive could not
have accommodated more than three or four sweaters. They resemble
the small 'caves', built into banks, in which many Irish natives
were reported to live in the seventeenth century.
Some have chinks
to let out the smoke, but they were necessarily cleared of fire
and ash before use - so any chinks (deliberate or otherwise) in
the rough construction would have served as ventilation ducts
in a cramped space. Where these were too big, they were stopped
with sods or with mortar.

Cornamore, county Leitrim
They were often
covered with sods of earth to counterweight and stabilise the
corbelling, and these would also have acted as insulation after
firing. That they were fired is certain, for soot remains on the
ceilings of some.

The first - and only detailed - account of Irish sweathouses came
from Latocnaye in the late eighteenth century: a man who spoke
no Irish. [A Frenchman's Walk Through Ireland, translation
reprinted by Blackstaff Press, Belfast 1984].
The rural Irishry who used
them would not necessarily have told such a man - or any Dubliner,
Anglo-Irishman or Englishman in a carriage - what functions the
sweathouses served. To this day, the rural Irish of the west (like
peasants everywhere) will tell tourists what they think they want
to hear, halving distances so as not to discourage the traveller,
and enthusiastically recommending the nearest café. Nevertheless,
reports of the Sweating Cure have been given recently to
Brian Williams of the Archæological Survey of Northern Ireland,
by people who are unlikely to have heard of it from the archæological
literature, or from outside their immediate area.

Ballydonegan, county Derry: beside a stream
A number of early writers on the Turkish bath quote the following
from the Reverend Robert Gage of Rathlin Island (between county
Antrim and the Mull of Kintyre in Scotland), who wrote:-
'Small buildings
called sweat-houses are erected, somewhat in the shape of a beehive,
constructed with stones and turf, neatly put together; the roof
being formed of the same material, with a small hole in the centre.
There is also an aperture below, just large enough to admit one
person, on hands and knees. When required for use, a large fire
is lighted in the middle of the floor, and allowed to burn out,
by which time the house has become thoroughly heated; the ashes
are then swept away, and the patient goes in, having first taken
off his clothes, with the exception of his undergarment, which
he hands to a friend outside. The hole in the roof is then covered
with a flat stone and the entrance is also closed up with sods,
to prevent the admission of air. The patient remains within until
he begins to perspire copiously, when (if young and strong) he
plunges into the sea, but the aged or weak retire to bed for a
few hours.'
[Gage: A History of the Island of Rathlin, 1851]
He also mentions
that young women use it for their complexion after burning kelp,
and that after about 30 minutes use, their skin is much improved.
The author could
find no websites devoted to the subject - just brief mentions
and a very poor photograph on one of the Irish tourist websites.
Because of their
great fragility, no sweathouse standing today is likely to be
earlier than the second part of the 19th century. If indeed they
were built at that time for prophylactic use or to ease rheumatic
pain, then (unless they were a curious 19th-century fad introduced
by an eccentric) they very likely had an earlier - and more effective
- function.
The first thing
to note is that the present distribution is in the poorest parts
of the ignored counties of Ireland: Fermanagh, Leitrim and Cavan,
as well as northern Sligo. They are often tucked away in rather
magical places, near little streams and/or in little brakes or
copses. This differentiates them from lime-kilns (also common
in central Leitrim and NW Cavan) which have a similar construction
but are much more easily accessible - and have even-smaller "entrances"
which only a stoat or a small dog could get through. The inhabitants
of this area were until very recently amongst the poorest and
most undernourished in Europe. They lived on potatoes and whey,
never saw fruit, and after the Famine of the 1840s brought a continuing
revulsion against the eating of anything wild and natural (e.g.
blackberries and elderberries, let alone sloes, wild damsons,
rose-hips, chickweed, nettles, sea scurvy grass, mushrooms etc.)
had almost no variety of diet. Healthy pre-Famine infusions gave
way to a dependence upon strong imported tea laced with imported,
addictive and teeth-rotting sugar: expensive items which allowed
little cash for real nourishment in a largely-subsistence society
where great labour was required simply to provide fuel for winter.
Mullan, county Fermanagh
Sweathouses were carefully built, often corbelled, but sometimes
slab-roofed, well away from permanent dwelling-houses and often
from tracks. They would have had to be tucked away from the eyes
of land-agents who might have charged rent on them. But they could
have been close to impermanent dwellings, such as bivouacs of
tarpaulin or rags and sticks, or "cabins" of wattle
and daub such as may have given the town of Cavan its name (like
several villages in France called Les Cabannes), rather
than the more pleasing derivation of 'hollow' now claimed. It
would have taken two or three skilled wall-builders two days to
find and select the stones and build one. Some townlands
(named units of land of very variable size usually smaller than
an English parish) had several sweathouses, and even now three
of four townlands have more than one sweathouse, intact
or ruined.
The corbel-roofing
goes back, of course, to prehistoric times, and is found in Neolithic
tombs all over Europe. It involves the laying of stones in an
ever-diminishing coil or spiral until it can be finished with
a single stone.

All sorts of corbelled rustic structures can still be seen across
Europe, with functions as various as hen-houses, dog-kennels,
shepherds' huts and stores. There
are hundreds in the French département of the Lot
and adjacent départements of Quercy-Rouergue, where
they are known as gariotes.

They all, however, have proper doorways, unlike the diminutive
entrances of Irish sweathouses. These required considerable labour
to heat. One report says that two donkey-cartsful of turf
(which is what peat is called in Ireland) was required to get
the stones to a high enough temperature for the sweating - and
this is probably correct. In a society where not everyone had
rights of turbary (the cutting of peat), and turf was burned in
an open hearth, piece by frugal piece, this was quite an extravagance.
Turf-digging is labour enough, but the throwing of it up the turf-bank,
the stacking in small piles to dry in a wet climate, and its transportation
to the dwelling-house still takes a several weeks of the summer,
and still many Irishmen working in Britain will come home in the
summer to help with the turf. The prodigal use of it to heat up
a sweathouse, presumably well away from the dwelling, suggests
that sweathouses were in some way very important.
