Multianalytical approach to the exceptional Late Roman shipwreck of Ses Fontanelles (Mallorca, Balearic Islands, Spain)

Abstract

The paper presents the results of an interim analytical approach to the Late Roman shipwreck of Ses Fontanelles recently found in the island of Mallorca (Balearic Islands, Spain). The excellent state of preservation of the hull and the cargo, including amphorae with painted inscriptions (tituli picti), and its location in shallow waters offshore of one of the main touristic beaches of the island makes this a unique finding in the Mediterranean. A first season of excavations and study of the cargo triggered an analytical approach to solve some of the problems pose by archaeological research, mainly related to the possible origin of the vessel. The analytical strategy combines petrographic analysis for the study of the provenance of the amphorae, archaeozoology and residue analysis to identify their content, and analysis of the wood and plant remains to understand the use of vegetal resources in shipbuilding and in the stow of the cargo. The results of the combination of the petrographic analysis, the study of the ichthyofauna and the organic residue analysis suggest that the boat probably departed from the area of Cartagena in the southeastern part of the Iberian Peninsula, carrying a cargo of fish sauce (liquaminis flos), oil, and wine (probably also some olives preserved in grape derivatives), transported in three main types of amphorae. The analysis of the wood shows, as known in Roman shipbuilding, a clear selection of forest resources. The shipbuilders used pine for longitudinal parts of the hull, while for the small pieces related to the assemblage system (pegged, mortise and tenons) and subjected to a great stress they selected harder woods mainly Cupressaceae, Olea europaea, and Laurus nobilis. In addition, the study reveals that mainly branches of Vitis vinifera, but also other herbaceous plants were used as dunnage protecting the cargo during the journey. The results help to shed some light into different aspects of this unique vessel sunk in Mallorcan waters and contributes to show the benefit of applying archaeological sciences in maritime archaeology.
