Reformist hagiography: the Life of St Roding of Beaulieu and the struggle for power in early eleventh-century Lotharingia

This article explores an example of ‘reformist’ hagiographic production in early eleventh-century Lotharingia by focusing on the Life of St Roding of Beaulieu, a small monastery in the diocese of Verdun. Until recently, this text was interpreted exclusively in terms of the scant information it provides for this institution's early medieval history and in terms of its ideological message regarding monastic discipline and leadership. By integrating the composition of this text into the then-current regional geography and political context, this article proposes a new approach to its interpretation and to the understanding of Beaulieu’s ‘monastic reform’ in general. Close analysis of the narrative reveals that its production was inspired by specific issues relating to local and regional politics in the mid-1010s, and that parts of the institution's recent history were veiled allegorically behind the portrayal of Roding. However, rapid changes in power relationships rendered those aspects of the text outdated within a few years. This raises significant questions regarding the long-term relevance of such hidden stories and the degree to which their ideological, political and other messages remained accessible to medieval audiences.     

OSL dating as an alternative tool for age determination of relic charcoal kilns

Chronometric studies of charcoal production remains are largely based on ¹⁴C-dating of associated charcoal. Owing to intrinsic limitations, however, this method provides no meaningful time resolution for post-1650 CE features. We investigate the potential of optically stimulated luminescence (OSL) dating of heated sandy sediments as an alternative and complementary tool for dating charcoal kiln remains. Seven samples from five relic charcoal kilns and 11 complementary samples from the underlying sandy substrate are used. Through a range of procedural tests, we demonstrate that the single-aliquot, regenerative-dose procedure in combination with OSL signals from quartz allows determining equivalent doses both accurately and precisely. For four of the five investigated kilns, OSL ages are consistent with independent age information from ¹⁴C-dating and written sources. Especially for post-1650 CE features, the precision can be significantly better than that of ¹⁴C-dating, and we highlight the potential of OSL dating for distinguishing, relatively, between charcoal production phases with an unprecedented time resolution. We conclude that the approach is a promising alternative to ¹⁴C.
