1 Chroniclers occasionally report the devastation with an unsettling matter-of-factness. ”2 Yet others, like the English compiler of the Flores historiarum under the year 1315 and a Salzburg chronicler portraying conditions in 1316, permitted themselves more dramatic expressions. 9 The open ﬁelds with heavy soils plowed in long furrows were capable of absorbing enormous amounts of water; and drainage did not cause erosion. So the despoiling referred to by the chroniclers signiﬁes the ap- H A R V E S T F AI L U R E S, A N I M A L M U R R A I N S 25 pearance of vast muddy tracts and sparse, beaten-down crops rather than the absolute ruining of the land.
Burial, however, seems also to have been practiced where continuous rains made outdoor ﬁres difﬁcult to sustain. Sometimes infected animals were simply thrown into deep abandoned wells. 101 The decline in the ruminant population from the pestilence was compounded in the period 1315–1318 by two other problems. First, in many places the persistent dampness meant that even if it was possible to mow the meadows, it was difﬁcult to cure (dry) the hay in the ﬁelds. On the one hand, to store uncured hay was to invite rotting and, worse, a buildup of heat and methane gas from the rotting hay, a buildup which by igniting any grain, straw, or hay that did manage to dry out would bring about the conﬂagration of wooden barns.
82 This tragic period was made more so by war. Although it cannot be said that war caused the famine, it intensiﬁed the deprivation by expanding a production crisis into a distribution crisis as well. No attempt will be made at this time to assess in detail the effects of the wars, a task that will be reserved for subsequent discussions of prices, wages, cost of living, mortality, and the like. Here we need only enumerate the conﬂicts and address a few of their most obvious and general consequences at the regional level in the principalities affected by the persistently bad weather.
