The article reports on a new sampling method and the archaeological context of cave drawings, which include the oldest currently known graffiti in the Czech Republic. Between 2016 and 2020, samples with a small amount of charcoal were taken from drawings found in Kateřinská Cave (Catherine’s Cave) of the Moravian Karst in the Czech Republic. A new gentle method of sampling charcoal from the cave walls was developed for the purpose of radiocarbon (14C) dating cave drawings of unknown age, while preserving the contours of the drawings. 14C analysis has provided data from four periods of prehistory and history: from the Neolithic around 5000 BC, the turn of the Neolithic and Eneolithic around 4300 BC, the Hallstatt Period from 800–450 BC, and also from the Middle Ages (13th century). The radiocarbon dates of the graffiti correspond to the dates of the pottery finds from the entrance portal of Kateřinská Cave, thus validating the dates and the sampling method.

在捷克共和国凯特因斯卡洞穴发现的史前木炭涂鸦

这篇文章报道了一种新的采样方法和洞穴壁画的考古背景，其中包括捷克共和国目前已知最古老的涂鸦。2016 年至 2020 年间，在捷克共和国摩拉维亚喀斯特地区的卡特琳斯卡洞穴（凯瑟琳洞穴）发现的图纸中提取了含有少量木炭的样本。为了放射性碳的目的，开发了一种从洞穴壁上采集木炭的温和的新方法（14C) 对未知年代的洞穴图纸进行约会，同时保留图纸的轮廓。14C 分析提供了四个史前和历史时期的数据：公元前 5000 年左右的新石器时代、公元前 4300 年左右的新石器时代和新石器时代之交、公元前 800-450 年的哈尔施塔特时期以及中世纪（13 世纪） . 涂鸦的放射性碳日期对应于从 Kateřinská 洞穴入口处发现的陶器的日期，从而验证了日期和采样方法。
