Signs are well documented in medieval Benedictine monasteries of Western Europe, from
Portugal to
England. Antique texts present lists of words with accompanying signs, including instructions for sign production. Occasionally they also explain the rationale behind the sign. Signs are mostly
nouns relating to monastic life. Foods, articles of clothing, particular rooms and buildings, ritual objects, and different ranks of clerical office dominate the vocabulary. The few signs that act as
verbs include "sit", "stand up", "kneel", and "confess". They almost always bear an
iconic or visually motivated connection to the thing represented by the sign. No grammar is described for these signs, and they were probably used in the
word order of an oral language—either
Latin or the local vernacular—and possibly with accompanying gesture such as pointing. Modern Cistercian monks in England or the
United States use a syntax derived "heavily, but not exclusively", from English, while Cistercian monks in
France loosely follow the syntax of the
French language; at least as much as it is possible to do so, given the limited lexicon. Vocabulary lists in the medieval texts ranged from 52 signs to 472, with "the average at 178 and a mean at 145." The earliest Benedictine sign books date from around 1075 (and again at about 1083) at the
Abbey of Cluny (in what is now France), and
Hirsau Abbey (in what is now
Germany) at around the same time.
Bonaventure in the thirteenth century used a finger alphabet, and the medieval
Monasteriales Indicia describes 127 signs used by Anglo-Saxon Benedictine monks. Signs from a sixteenth century Portuguese monastic sign language have also been documented. ==List==
