In 2008 a naval ram, decorated with swords (Kopis and Xiphoi) was recovered by the Soprintendenza del Mare off Acqualadroni in Messina. This ram was initially attributed to the Battle of the Naulochus and dated to the first century BC in a preliminary study (Tusa,Buccellato 2011). In 2013, additional evidences like metal analysis of the spikes, chemical analyses on the timbers, and an new C14 algorithms OxCal dating placed the construction to the 3rd century BC (median 287-279 BC), in the context of the First Punic War (Tisseyre 2013). We propose a new possible interpretation of the internal arrangement of the timbers in the ram, characterized by the presence of one or two internal metal sheaths. Furthermore, through a study on the construction and mounting of the ram on the ship, we proposes a new construction technique of the assembly.
