This study presents results from stable isotope analyses of a modern stalagmite and three soda straw stalactites from Kapsia Cave, the Peloponnese, Greece. The resulting values from the stalagmite are put into context of local meteorological data, as well as previous research from Kapsia Cave. The potential for using soda straw stalactites as complementary climate archives on shorter time scales on the Peloponnese is also explored. The isotopic values in the stalagmite confirm a strong link to the amount effect on an annual scale. On a seasonal scale, variations in the isotopic signal can be detectedas a result of i.e. increased cave air temperature in summer. The stable isotope values in the soda straw stalactites largely correspond to previous isotopic measurements in Kapsia Cave. The trend of the isotopic carbon signal in two of the straws also strengthens earlier theories suggesting a link to CO2 concentrations in the external atmosphere. Soda straws are, thus, encouraged for use in future climate studies, although the sampling method should be further explored. The results of this study contribute to an increased understanding of Peloponnesian speleothems in relation to environmental processes and new insights are suggested into the use of soda straw stalactites as climate archives.

Au sein de la principauté de Morée, fondée à la suite de la quatrième croisade parquelques chevaliers francs dans les territoires de l’ancien empire byzantin, hommes et femmes de l’élite latine participent au maintien de la domination pendant près de deux siècles et demi. S’inspirant des nouvelles tendances de la recherche telles que l’étude des individus par la prosopographie, l’histoire des représentations et du pouvoir des femmes, cette monographie s’attache tout particulièrement à mettre en évidence la place, le rôle et le pouvoir des dames de la Morée franque, du XIIIe au XVe siècle. Au-delà des lieux communs fournis par la pensée médiévale, essentiellement masculine, il s’agira d’analyser l’implication des dames dans les alliances familiales, dans la transmission et la gestion dupatrimoine féodal ou encore dans la vie politique, économique et sociale de la principauté. Organisé en trois parties, ce travail examine d’abord la représentation du féminin dans les sources latines et byzantines, puis il considère la place des dames au sein des familles et des stratégies matrimoniales, enfin il étudie le rôle et le pouvoir de ces femmes dans la féodalité moréote et le gouvernement de la principauté. / Within the principality of Morea, founded after the Fourth Crusade by Frankishknights in the territories of the former Byzantine Empire, men and women of the Latin elite ruled for nearly two and a half centuries. Drawing on new research trends, such as the study of individuals in prosopography, the history of representations and of women's power, this monograph highlights the place, role and power of the ladies of Frankish Morea, from the 13th to the 15th century. Going beyond the commonplace, mostly male, perpectives reflected in medieval thinking, it will analyze the involvement of women in family alliances, in the transmission and management of feudal holdings, and in the political, economic and social life of the principality. Presented in three parts, this work first examines the representation of women in the Latin and Byzantine sources, thenconsiders the place of women in the family and marriage strategies, and concludes by studying the role and power of women in Moreote feudal and government structures.
