Using intestinal parasites to identify the utilization of archaeological structures: A 12th-13th century sewer systems from an Islamic funduq (Murcia, Spain)

Abstract

The discovery of specific parasites in archaeological contexts provides unique insights into the hygiene, sanitation, and socioeconomic dynamics of ancient populations, as well as their patterns of mobility. Paleoparasitological evidence offers a window into the spread of infections across different regions and time periods. This investigation leveraged paleoparasitology to explore the utilization of archaeological structures, specifically the water drainage system of a 12th-13th century funduq in the ancient Islamic city of Murcia, Spain. Through a systematic analysis, parasitic findings were compared with archaeological evidence, revealing a strong correlation between the presence of roundworm and whipworm eggs in wastewater channels and their functional role. In contrast, the absence of parasitic eggs in the clean water system further confirmed the distinct purposes of the pipes. This approach confirms paleoparasitology as a powerful tool for interpreting the use of ancient infrastructure.
