2024 Dana Grant Report: Modeling Punic Space at Motya
Jason Herrmann, University of Pennsylvania and Paola Sconzo, University of Palermo
Ancient Motya (modern Isola San Pantaleo, Sicily, Italy), founded in the late 8th century BCE by Phoenician wayfarers, was a significant hub in the central Mediterranean, serving as a crucial point of contact between Carthage and Sicily at the city鈥檚 height in the 5th聽century BCE. Unlike many other Phoenician-Punic urban centers, Motya has remained largely undisturbed by subsequent occupations, offering archaeologists a rare and valuable opportunity to study Punic urban planning in its original context.
Since 2017, we have been conducting comprehensive geophysical surveys on the island for the Space and Identity at Ancient Motya project. Our goal is to map the layout of the city鈥檚 structures and to use their configuration to interpret Motya鈥檚 social organization and expressions of ethnic identity. This project is a collaboration between the University of Palermo and the Penn Museum and operates as a subproject under the University of Palermo Archaeological Mission to Motya, with the support of the Superintendency for Cultural and Environmental Heritage of Trapani.
Fig. 1. Motya was situated on an island in the Marsala Stagnone in western Sicily. By the 5th century BCE, the fortified city of Motya covered the entire island and was connected to the Sicilian mainland by a causeway, now submerged and visible in the foreground of the above image.

Thanks to the support of the ASOR Stevan B. Dana Grant, our multidisciplinary project was able to continue with the assistance of an international team of eleven students from the University of Palermo and the University of Pennsylvania. These students contributed to both the geophysical survey and the ongoing excavations carried out toward two primary objectives. The first was to expand the geophysical survey coverage beyond the areas that were accessible for magnetic gradiometry in previous years. To this end, ground-penetrating radar (GPR) and electrical soil resistance helped to document subsurface features where vegetation or other surface conditions made magnetic gradiometry unfeasible.
Our second goal was to further investigate ambiguous features observed in the magnetic gradiometry that required additional clarification. One area of particular interest was a depression in the northeast sector of the island where magnetic data were inconclusive. Here we employed GPR, a technique that measures how radio waves are reflected off changes in the textures of buried materials. Preliminary results show that, unlike the rest of the island, this area was not covered with streets and houses during Motya鈥檚 urban expansion, suggesting that it was reserved for some special purpose.

Features observed in the geophysical data from previous seasons were verified through test excavations, including a deep pit that was visible in the magnetic gradiometry data and seemed to date to the early 6th and 7th centuries BCE.

We were also interested in determining the depths of key features across the island to aid the development of a digital reconstruction of the ancient city and landscape. For this, we combined GPR with electrical soil resistance, a method that measures the ease with which an electrical current travels in sediments, to measure the depth of streets that had been previously mapped in the magnetic data. Unlike magnetic gradiometry, GPR and electrical resistance data allow for precise estimation of the depths of the observed features, providing critical information for reconstructing the ancient city’s layout.
We thank ASOR and the Stevan B. Dana project grant for enabling broad student participation in our 2024 field season. Because of this support, we have been able to come closer to a complete map of Motya鈥檚 ancient urban plan with geophysical survey and have been able to verify some of the features we observed in the geophysical data through excavation. This information, supported by data from aerial surveys, surface collection, and legacy excavations is enabling us to develop detailed interpretations of the use of space for multiple phases of the life of ancient Motya, and establish a strong foundation for future work on this island site.
