Given the nature of medieval artifacts and resulting research requirements, a precise temporal classification is essential. It is especially important for the purposes of medieval archaeology in interpreting archaeological finds/finding situations and identifying them with a historical events or figures, for example, to identify skeletal remains of a known historical figure or to establish a chronological sequence of various cultural and architectural changes within an area. Due to the fact that the uncertainties of radiocarbon (14C) analyses have been decreasing in recent years, the applicability of 14C dating for such purposes is now growing. In this work, we aim to demonstrate the current possibilities of the use of AMS 14C analyses on specific cases and confront the results with other available data. 14C data from skeletal remains of members of the oldest Czech ruling dynasty of the Přemyslids (about 880–1306 AD) were obtained in recent years. Archaeological research conducted in the three oldest churches in the Prague Castle discovered skeletal remains of three members of the second, two members of the fourth and two members of the fifth generation. This case study of the application of 14C data has three parts: i) identification of excavated individuals; ii) demonstration of the application using current AMS-based analysis of 14C on medieval osteological material and tests of our preparation method; iii) contributing to discussion and consulting with other problematical 14C age alteration influenced by diet, age of bone collagen or seasonal variation of 14C activity. The obtained results and the issues arising from them clearly highlight the necessity of a multidisciplinary cooperation in this type of study.

中世纪早期波希米亚和放射性碳数据的最古老规则

鉴于中世纪文物的性质和由此产生的研究要求，精确的时间分类至关重要。对于中世纪考古学而言，解释考古发现/发现情况并将其与历史事件或人物识别特别重要，例如，识别已知历史人物的骨骼遗骸或建立各种文化和建筑的时间顺序区域内的变化。由于放射性碳的不确定性（14C) 分析近年来一直在减少，适用性14用于此类目的的 C 约会现在正在增长。在这项工作中，我们旨在展示当前使用 AMS 的可能性14C 对特定案例进行分析，并将结果与​​其他可用数据进行对比。14近年来，从捷克最古老的普热米斯王朝（约公元 880-1306 年）成员的骨骼遗骸中获得了 C 数据。在布拉格城堡三座最古老的教堂中进行的考古研究发现了三名第二代成员、两名第四代成员和两名第五代成员的骨骼遗骸。本案例研究应用14C 数据包括三个部分： i) 挖掘个体的识别；ii) 使用当前基于 AMS 的分析来演示应用程序14C 关于中世纪骨学材料和我们制备方法的测试；iii) 与其他有问题的人进行讨论和咨询14C 受饮食、骨胶原年龄或骨胶原的季节变化影响的年龄变化14C 活动。所获得的结果和由此产生的问题清楚地突出了此类研究中多学科合作的必要性。
