Bloodletting was a preventative and restorative treatment frequently
administered during the Middle Ages. It was thought to restore
balance to the body, to sharpen the senses and clear the brain;
it was also believed to produce a musical voice, to promote longevity
and quench sexual desire. Bloodletting in Cistercian abbeys,
as in other religious houses, was a routine part of life. As
a matter of course monks were bled several times a year, to keep
them in optimum health; those who were ill might then receive
extra bleedings to restore them to health. The monks were bloodlet
in batches at least four times a year – February, April,
June and September. There was to be no bloodletting at harvest,
when everyone was needed to help in the fields, or at feasts
when the entire community was expected to participate in all
the services.
The process
The body of an adult male contains approximately
9 1/2 pints of blood. During a modern blood donation session
about 3/4 pint (450ml) is removed.
The bloodletting took place in the
warming-house, usually in the late morning or early afternoon.
A fire was lit in preparation
and the monk could have a bite to eat in the refectory before
undergoing
the procedure; he would certainly need this extra sustenance
for the monk was drained to the point of unconsciousness
and might
lose up to four pints of blood. This weakened him considerably
and he required time to recuperate. In the twelfth century
this recovery time was spent in the dormitory, cloister and chapter-house,
but from the early thirteenth century the monk rested in the
infirmary where he enjoyed a more relaxed diet and relief
from
the daily
round of work and liturgical offices. During this recovery
time, the monk did not participate in the chants; nor did he read.
Any monk who held an office (obedientiary) was not expected
to carry
out any of his duties; his deputy filled in. This exemption
did
not, however, apply to the main office-bearers, namely, the
prior, sacrist, cellarer and novice-master. On the third day after
the
bloodletting, the monk joined the rest of the community for
some of the Offices and might read in the cloister; on the fourth
day he was expected to play a full part in the daily life,
although
he did not necessarily engage in manual
labour.
