Book Reviews The Mills of Medieval England. By Richard Holt. Oxford and New York: Basil Blackwell, 1988. Pp. x + 202; illustrations, notes, appen dixes, bibliography, index. $55.00. Richard Holt has provided historians of technology, as well as those who study broader social and economic issues, with a rigorous, comprehensive coverage of medieval England’s use of mills powered by water, wind, and horses. Beginning with the water mill, he shows that the simultaneous rise of the horizontal and vertical types was an accomplishment occurring centuries before the arrival of William the Conqueror. The spread of the 6,082 water mills reported in William’s Domesday Book was uneven and stimulated more by geographical factors than the isochronal patterns of diffusion recently suggested by Roger Reynolds. Variations in their estimated worth were also geo graphically determined: high-value mills were found on the major rivers near the higher densities of population, while those of low value were situated on the less significant watercourses and catered only to a few local inhabitants. In the approximately one hundred years following the Domesday Book (1086—1189), some water mills went out of use, to be replaced by others that generated greater revenue. During these years, water mills not only grew in value but also modestly in number, as indicated by the increase of the twenty-eight mills on the manors of the Glastonbury Abbey to thirty-one. The uneven distribution of water mills throughout England none theless remained. Horse mills, known since antiquity, could have been employed in areas where there was an insufficient supply of water, but Holt finds this to be purely speculative since the earliest reference to such a device in England is 1183. A more uniform dispersal of the edifices that ground the country’s grain came with the introduction of the windmill mounted on a post so that, when it turned, its vertical sail yards could take advantage of the currents of air. Contrary to Edward J. Kealey’s recent opinion that windmills of this sort first arrived in England between 1086 and 1137, Holt discovers the new mechanism appearing shortly before 1189 on both sides of the North Sea and English Channel. The post mill, invented in that area and diffused more than likely by seaborne travelers in touch with communities quite familiar with sailing ships, was not immediately accepted in great number, probably because of technical deficiencies. The 1230s and 1240s, however, witPermission to reprint a review printed in this section may be obtained only from the reviewer. 508 TECHNOLOGY AND CULTURE Book Reviews 509 nessed an extraordinary increase, particularly in those areas where adequate waterpower was lacking. In 1086, for example, the dry parts of Cambridgeshire had only two mills that were run by water, while in 1279 they possessed thirty-nine moved by wind. Although windmill building virtually ceased in England’s eastern counties after 1279, they continued to increase in the west and north of the country. Despite favorable geographical circumstances, southwestern England was the only area where a definite lack ofinterest in the windmill was displayed. With the proper distribution of the mills of medieval England established by means of clear, convincing statistics, Holt turns to their administrative, financial, and technological development. Some of his conclusions are indeed enlightening. Contrary to the views of Marc Bloch and Pierre Dockes, the obligation to use a lord’s mill because of his seigneurial or banal rights was highly flexible. Owing to the considerable number of independent mills held in hereditary free tenure or owned outright by knightly families, tenants of whatever status could take their grain where they pleased. If villeins were compelled to a suit of mill, they would risk being fined or simply pay for permission to use another edifice. The alternative of the hand mill was there, but mechanical milling was preferred. The only objection was the required toll, which for the villein could be extortionate. Moreover, the millers of these competitive establishments are not to be equated with their boisterous fictitious counterparts in Chaucer’s Canterbury Tales. As demesne servants, they received low salaries fortified by allowances or, in place of these remunerations, propor tions of the toll. If they...
