Objective: This study aims to describe various types of skeletal lesions and lesion patterns observed in five potential cases of treponematosis from the same archaeological site. Material and methods: The study examines five adult skeletons recovered from Santa Maria do Olival, Tomar, Portugal. Macroscopic observations were conducted on all remains, supplemented by relevant radiographic investigations. Results: The analyzed individuals exhibited diverse types of skeletal lesions and distinct patterns of lesion distribution. Radiocarbon dating of two of these skeletons locates them chronologically close to the beginning of the colonial period (15th century). Discussion: The findings indicate considerable variation in the lesions and lesion patterns associated with treponematosis, even within the same archaeological site. The radiocarbon data implies the presence of pre-Columbian treponemal disease or a rapid progression to the tertiary phase of the disease. This study represents the oldest cases of treponematosis in Portugal and the only one with more than one individual affected from the same archaeological site. Considering Portugal's prominent role in the European Age of Exploration, the study underscores the significance of pathogen exchanges between Europeans, South Americans, Africans, and Asians. Future investigations should reassess Iberian osteological collections from this time period, given the historical importance of Portugal and Spain in the intercontinental movements.
