FACILITIES FOR STORAGE AND
THRESHING OF GRAIN
V.14.1
THE MAIN GRANARY
Between the Great Collective Workshop and the Gardener's
House is a large Granary (fig. 431) for storing the annual
harvest and threshing the grain:
Frugibus hic instat cunctis labor excutiendis
Here is pursued the labor of threshing the entire
harvest
The draftsman takes great care to define the two complementary
functions of this building: the first, with an
inscription, "barn, i.e., storehouse for the annual harvest
of grain" (horreum um repositio fructuü annaliū);[462]
the second,
by designating a cross-shaped area of ground as "the area
where grain and chaff are threshed" (area in qua triturant'
grana et paleae).
The Granary is 47½ feet wide and 90 feet long. Its axis
runs from south to north. The building has only one
entrance, in the middle of its western long wall; it is a
double-winged door wide enough to allow the loaded
wagons to enter. It is not likely that a barn of these dimensions
would have been covered by a single span in the
ninth century. Even in the great monastic barns of the
thirteenth century the roof was carried by two rows of
freestanding inner posts when the width of the barn exceeded
25 feet. The draftsman must have taken these constructional
features for granted. Had the Granary been intended
to shelter human beings or animals as well, the floor plan
would have indicated the wall partitions separating the
spaces used for storing the harvest from the spaces reserved
for people or animals; and the course of these partitions
would, in turn, have given us a clue to the location of the
roof-supporting posts. But the barn of the Plan of St. Gall
had no such secondary function, except that a certain
amount of its floor space had to be kept vacant for threshing.
The draftsman makes this clear by carefully delineating
the surface area needed for this purpose: two threshing
lanes intersecting each other at right angles, each lane about
12 feet wide, i.e., the distance two rows of men would
require when flailing grain from opposite sides.
The layout of the Granary of the Plan of St. Gall teaches
us that broadside access must have been a very common
feature, if not the standard form, in Carolingian barn
construction. It was and remained throughout the entire
Middle Ages the traditional form of monastic and secular
English barn construction. In medieval France and in the
medieval and post-medieval dwelling barns of Lower Saxony
the entrances were invariably in the gable walls. In the
Lowlands and in southern Germany—as a glance at the
engravings of Pieter Bruegel the Elder or the watercolors
of Albrecht Dürer (figs. 335; 336) show—the two types are
mixed.
A typical English parallel comparable in size to the
Granary of the Plan of St. Gall is the priory barn of Little
Wymondley, Hertfordshire (fig. 434A-C)[463]
, probably dating
from the first half of the thirteenth century. Other examples
of the same period, both English and Continental, were
discussed above on pp. 103ff. The earliest evidence, other
than the Plan of St. Gall, for monastic barns with broadside
entrances are the barns that the Dean and Chapter of the
cathedral of St. Paul's in London maintained on its outlying
estates in the counties of Hertfordshire, Essex, Middlesex,
and Surrey. They are described in lease agreements
dating from 1114 to 1155.[464]
A careful reading of these texts
makes it clear that traditionally the harvest was stored in
this type of barn by filling the bays closest to the gable walls
first and working from there toward the center of the
building, the center bay being left empty for the entry and
exit of the wagons. This center bay was thus the natural
place for threshing. In many of the surviving English
medieval barns these entrance bays are paved, either in
stone or with wooden planks, and were used for threshing
until the invention of modern harvesting machinery[465]
eliminated the need for any such provisions (cf. fig. 437).
Our reconstruction of the Granary of the Plan (fig. 435AE)
is not modeled after any particular example. We have
chosen a type that might have been found anywhere at any
time during the Middle Ages. We have given it a roof with
rafters of uniform scantling and hipped bays at the end,
because of the restraining effect such lean-to's exert on
any tendency of such a roof to give way under longitudinal
stresses. We could also have reconstructed it as a purlin
roof, analogous to Little Wymondley, except for the curved
arch and wind braces of this building which are typically
English and have no parallels on the Continent.
The Granary of the Plan of St. Gall was the storage
place, I should imagine, not only for the harvest yielded
by the fields that the monastery worked with the aid of its
own serfs, but also for the revenues obtained through the
tithing of land leased out to tenants.[466]
The volume of the
annual revenues derived from any of these sources was a
carefully regulated matter. Abbot Adalhard of Corbie, who
had to take care of a monastic community of an average of
300 souls, furnished a detailed account of the manner in
which the supply of grain was handled in his own monastery.
The total income in grain "well winnowed and husked"
(spelta bene uentilata et mundata) was 750 baskets per year
(two baskets per day plus 20 additional baskets for safety).[467]
Abbot Adalhard informs us that two baskets average ten
modii, each modius yielding 30 loaves of bread; two baskets
thus giving assurance of 300 loaves per day. He establishes
how many sheaves make up a modius of grain, allowing for
the variation in quality of grain obtained from different
fields, and he draws attention to the detrimental effect of
such variance on the attempt to attain an accurate system
of measurement. He points out that the straw ought always
to be delivered with the grain, as it, too, has uses, and he
rules that when places are too far away for the tithe to be
carted in, the villages lying near should pay double tithes
and then collect from their neighbors farther out. In conclusion,
he admonished the Porter, who is in charge of all
these operations, to keep an accurate inventory of all these
deliveries.[468]
V.14.2
THE BREWERS' GRANARY
The Monks' Brewery has its own granary with bins for the
storage of grain and other ingredients used in brewing.
This facility is attached to the south end of the House of
the Coopers and Wheelwrights and lies directly between
the Monks' Bake and Brew House and the buildings that
contain the machinery indispensable in the process of
brewing, the Drying Kiln and the Mortar. The Brewers'
Granary is a square, 32½ feet by 35 feet, internally divided
into a cross-shaped floor, which leaves four storage bins in
the corners (fig. 436).
The purpose of the building is explained by the following
title:
granarium ubi mandatu frumentum seru & ur & qđ
ad ceruisā praeparatur[469]
The granary where the cleansed grain is kept and
[where] what goes to make beer is prepared
The title implies that the grain used for brewing was subjected
to special cleaning and husking practices, which is
also suggested by the above-quoted passage from the
Statutes of Adalhard of Corbie, where it is stipulated that
the grain should be delivered to the monastery "well
winnowed and husked." The other ingredients referred
to in the title must include hops (
humblo), to the delivery,
reception and distribution of which, in the monastery of
Corbie, Adalhard devoted an entire paragraph.
[470]
The storage bins in the four corners of the Brewers'
Granary are designated as "repositories of these same
things—likewise" (repositoria eorundem rerum—similiter).
There is no unequivocal reference to threshing in the
inscriptions of this building, unless the word seru&tur be
interpreted to imply this activity, but the cruciform shape
of the floor space left between the bins, by analogy with the
threshing floor in the large Granary, suggests that the grain
used in brewing might have been threshed in its own
granary.

438.X SITE PLAN
The alignment of installations for grinding, crushing, and parching grain (27, 28, 29) at the southern edge of the monastry complex appears to
have been purposeful. If the topography of the site were ideal, with stream and land gradient permitting the development of water power, these
facilities on the Plan could all have been water driven. (A reconstruction of the presumptive waterways of the Plan is suggested, I, 74, fig.
53; and Horn, 1975, 228, fig. 4.
The Drying Kiln, Mortar, and Mill are sited next to the Monks' Bake and Brewhouse (9) and the Monks' Kitchen (8), and near the Bake
and Brewhouse of the Pilgrims and Paupers (32). Traffic patterns and usage demonstrated that the location of mills and mortars was carefully
planned. The Monks' Bakery and Kitchen required flour from the Mill; the Mortar produced crushed grain for brewing and for many other
dishes basic to the monks' diet. The Drying Kiln was used not only for parching grain but for drying fruit.
The noise of the mortars and mill would also have made it desirable to locate them at a distance from the center of monastic activities.
