Abstract

A small ivory head of a tonsured man, expertly carved in relief, was found in 1991 during excavations at the great eighth-eleventh century Lombard monastery at San Vincenzo al Volturno. The head was excavated with other fragments of carved ivory, antler and bone, in the vicinity of the collective workshop of the monastery, and was doubtless carved in this workshop. The head-type is a variant on an early Byzantine formula which was employed in Rome by the sixth century and subsequently, in the eighth century, was adopted by artists working for noble Lombard patrons in northern Italy. The painters responsible for decorating the churches and claustral buildings of San Vincenzo in the first half of the ninth century also used this type, and in details of its carving the new ivory head seems to show the direct influence of painted heads of early ninth-century date from the walls of the monastery. The relief was probably intended for the embellishment of a small casket or the cover of a book. The new head, besides being a significant addition to the tiny corpus of surviving carvings in ivory from early medieval Italy, shows the craftsmen in the monastery's workshop had at their disposal a material which was both rare and prestigious in the period.  相似文献

FLAX-RETTING POOLS, hitherto unrecognized, still survive in the landscape of NW. England, in close association with fulling-mill sites, tenter banks and simple potash pits. The retting-pool sites have common characteristics—usually on flat land; close to a river, but utilizing small streams which have been channelled to provide a controlled water supply; and raised banks for the drying of the retted flax. The field evidence occurs in documented contexts which show that a widespread linen industry was contemporary with, and often linked to, the 12th- and 13th-century demesne woollen industry.  相似文献

Previous interpretations of medieval moated sites, rooted in functionalist and culture-historical theoretical frameworks, describe moat owners as defending themselves from threats of physical violence or emulating a fashionable status symbol. This study takes an alternative framework by exploring moated sites’ active role in producing medieval ideologies of inequality. A set of case studies from the eastern Weald in south-east England provides evidence for how moats alter patterns of movement, produce spaces of stratified accessibility, and enhance the visibility of structures and spaces bounded by moats. Spatial data from surface survey is synthesized with historical context and ‘imagined’ moated spaces found in pictorial and textual sources to determine how moats may have been perceived by different groups of people in medieval society. By altering the physical and symbolic landscape, moated sites constituted the authority of their owners and contributed to the maintenance, or in some cases contestation, of medieval structural inequalities.  相似文献

BUILDING ACCOUNTS for 1398–99 give detailed costs of the construction of a circular, brick, free-standing artillery tower. The artillery towers at Southampton and Canterbury were linked to existing wall circuits, and detached forts in France may be more comparable to the tower at Norwich.  相似文献

This article demonstrates the relevance of future discounting behavior to studies of prehistoric subsistence strategies. The case study of Agave spp. bajada cultivation among the Classic Period, a.d. 1150–1450, Hohokam of southern Arizona illustrates how slight discounting of future rewards can significantly alter agriculture investment strategies. Despite a higher kcal/hour return than maize agriculture, agave cultivation lessened or ceased in several communities during a time in which intensification would be predicted due to inferred subsistence stress. We surmise the decade-long maturation of agave made it unattractive relative to more immediate return resources in any context that presented risks to land tenure. The cessation of agave cultivation can be understood on two levels of explanation. The long-term investments required by agave and tendency to discount future rewards are the ultimate causes. Political and social instability during the tumultuous Classic period, causing increased insecurity in land tenure, are the proximal causes.  相似文献
