The Latin Church of the West facing the Challenge of Islam during the Council of Basel (1431-1449) with special regard to John of Ragusa (d. 1443). Edition and Interpretation of New Sources in the Light of the Interactions on the Council and its Self-Conc

在巴塞尔会议（1431-1449）期间，西方教会的主要神学家在欧洲中部会面。君士坦丁堡陷落后（1453年），也就是大公会议结束后的几年，这些学者就伊斯兰教的角色进行了激烈的辩论，不仅是政治上的，而且是神学上的挑战。这一点经常得到检验。然而，巴塞尔理事会期间的初步工作和讨论，使这种即时反应成为可能，从未被系统地分析过。关于哪些来源仍然存在的深入研究也缺乏。然而，存在着丰富的材料，如信件、手稿、旁注，甚至巴塞尔理事会副主席约翰·拉古萨（1443年）的论文《Machumeto et Sarracenis》。对于1453年之后写的许多作品，也可以表明它们的作者在几年前就已经在处理伊斯兰教了。因此，本项目将以拉古萨的约翰（John of Ragusa）的相关著作为起点，出版新的资料来源，系统地研究和描述巴塞尔会议时期关于伊斯兰教的讨论。除了历史问题之外，更系统的主题将是大公会议的神学概念如何影响了关于伊斯兰教的讨论的问题，考虑到第二次梵蒂冈大公会议（1962-1965）及其对宗教对话的重要性，这个问题今天仍然具有相关性。

During the Council of Basel (1431-1449) the leading theologians of the western church met in the middle of Europe. After the fall of Constantinople (1453) and thus only a few years after the end of the council the same scholars intensively debated the role of Islam not only as a political, but also as a theological challenge. This has often been examined. However, the preliminary works and discussions during the Council of Basel, which enabled this immediate reaction, have never been systematically analysed. A thorough study about which sources are still existing is lacking, too. Yet, there exists e. g. rich material in form of letters, manuscripts, marginalia and even a treatise Machumeto et Sarracenis of the vice chairman of the Council of Basel, John of Ragusa (d. 1443). For many of the works written after 1453 it can also be shown that their authors had already been dealing with Islam in the years before. This project will thus publish new sources and systematically examine and describe the discussions about Islam in the time of the Council of Basel, taking the relevant works of John of Ragusa as starting point. Besides the historical problematics the more systematical subject will be the question how the theological concept of the council did influence the discussions about Islam, a question, which is still relevant today, taking into account the Second Vatican Council (1962-1965) and its importance for the dialogue of religions.
