with the religious foundation of Cosa. The exact meaning behind this find is undetermined, the source of much controversy and skepticism. Unidentified temple The remains of an unidentified temple lie on the crest of the Arx by the south wall of the Capitolium. For the most part, the remains have not been excavated; the original building was obliterated in antiquity after destruction by fire. The temple was not rebuilt, leaving only Temple D and the Capitolium at that time (middle of the 1st century BC). Though the burning itself does not imply a battle, the subsequent construction of fortifications may suggest some sort of attack. Scholars have only been able to identify this building through traces of walls and fragments of its terracotta decoration. These remains included two subtypes of antefix, one featuring a bust of Minerva and the other Hercules. The temple has thus been attributed to Jupiter, both Minerva and Hercules being offspring of the god. Much speculation arises, however, as the gods held a wide variety of contexts in Italy. Furthermore, when the site was further explored in the 1960s, no more traces of the temple were found. Temple D Dating to the late 3rd century BC, Temple D was located opposite the north angle of the Capitolium's forecourt and was oriented SE. It supported a single square cella. Temple D has been identified as being dedicated to the Roman-Italic goddess Mater Matuta, though this conclusion remains speculative. Architectural remains A great deal of important terracotta fragments have been found at Cosa and the Arx. They suggest various phases of temple decoration and redecoration and include (among others) pedimental structures and revetment plaques. Most of the remains date from the late 3rd century to the early 1st century BC. They display similar qualities as finds from Latin and Etruscan sites in Hellenistic Italy. Dyson holds that these evolving styles and similarities reflected the influence of the larger Hellenistic Mediterranean world that Rome was beginning to dominate. Two sets of these remains clearly belong to the earliest buildings (the Capitolium and Temple D), however, there is a third unidentified set. Scholars have used this set to explain the hypothetical Temple of Jupiter discussed earlier. Temple A Temple A consisted of a terraced podium and was oriented southwest. It was roughly the same size as the Capitolium with its forecourt, measuring 43 x 28 meters. The polygonal masonry of
