We present the first study employing Bayesian modelling of isotopic measurements on dentine increments (five human upper first molars) to address Romano-British infant feeding practices at Bainesse (UK). The stable carbon and nitrogen isotope results modelled to 6-month intervals with novel OsteoBioR software revealed some common patterns, with weaning not starting before the age of 6 months and higher animal protein consumption after the age of seven. The latter possibly indicated a ‘survival’ threshold, evidenced by historical sources and osteological data, hence marking a rise in social status of children. The important role of Bainesse as commercial hub in relation to the fort of Cataractonium does not exclude a priori the possibility that medical treatises and Roman culture were known at the site. However, our results also showed significant intra-individual differences with weaning cessation taking place between 2 and 5 years, suggesting that these were followed only partially and other aspects influenced family decisions on infant feeding practices in Bainesse.

通过增量牙本质同位素数据的贝叶斯建模研究 Roman Bainesse 的婴儿喂养策略

我们展示了第一项采用贝叶斯模型对牙本质增量（五颗人类上第一磨牙）进行同位素测量的研究，以解决在拜内斯（英国）的罗马-英国婴儿喂养实践。使用新型 OsteoBioR 软件模拟 6 个月间隔的稳定碳和氮同位素结果揭示了一些常见模式，在 6 个月大之前未开始断奶，7 岁之后动物蛋白消耗量增加。后者可能表示“生存”阈值，历史资料和骨学数据证明了这一点，因此标志着儿童社会地位的提高。Bainesse 作为商业中心的重要作用与 Cataractonium 堡垒有关，并不能先验地排除医学论文和罗马文化在该地点为人所知的可能性。然而，
