Unfree people in the Roman world could not legally marry, while they could in the Middle Ages. This paper explores the marriage of the unfree in the Carolingian empire (750–900 CE), a society with an intense moral concern about marriage. Carolingian churchmen wrote extensively about marriage, using a strongly gendered discourse focusing on how men should approach marriage and behave as husbands. However, these moral and legal texts rarely discussed unfree marriage, even though the practice was common. It is argued that this silence reflects the persistence of late antique class-based gender models, in which masculinity was reserved for married property holders. Although legal prohibitions on unfree marriages had ended, Carolingian moralists continued to be influenced by patristic assumptions that these were not valid relationships. These assumptions, combined with Frankish social practices that largely excluded unfree men from other key male roles, such as arms-bearing, meant that unfree husbands were not conceptualised as sufficiently ‘manly’ to have their marriages discussed. It is only from the tenth century onwards, when images of masculinity began to fragment more along lines of social status, that authors began explicitly to state that the Christian ideas of marriage applied to all, free and unfree.  相似文献

Tel Megiddo is a major type-site for the Middle Bronze in the Levant. During this period a new burial custom appeared in which the dead were interred beneath occupied houses. This tradition is well attested in Area K at the site. Area H, near the palatial complex, revealed a monumental masonry-constructed chamber tomb. This article presents the results of residue analysis conducted on ceramic vessels placed in these tombs as burial offerings. Hundreds of intramural Middle Bronze tombs with ceramic offerings were excavated in the Levant, but this is the first time the content of the vessels is revealed.  相似文献

This paper focuses on the identification of three sets of relationships exhibited by a time series of age-specific national migration rates and multiregional transition probability matrices: the relationship across time for the same age group, as defined by period (temporal) transformation coefficients or matrices; the relationships across age at a particular moment in time, as defined by age transformation coefficients or matrices; and the relationships across time and age, as defined by cohort transformation coefficients or matrices. Given any two of these relationships one can solve for the third. This feature of age-period-cohort relationships has a practical application in the development of improved methods for representing structural change in migration patterns over time and for indirectly estimating migration patterns using inadequate data.  相似文献

For over 3 years the Alberta government and the California Public Utilities Commission engaged in a bitter dispute over the future of the Alberta-California natural gas trade. This article examines how both sides sought to use their regulatory authority to control the substance of gas trade restructuring. It assesses the dispute as an exercise in deregulatory policymaking and suggests the need for increased study of the role and motivations of subnational regulatory actors.  相似文献
