L. & Lanza, M. & Lepone, A. & Scalici, M. & Trentacoste, A. & Zaccagnino, C. "New Excavations in the Urban Area of Caere."

Excavations conducted by Queen’s University in the central area of the Etruscan city of Caere, near the so-called hypogaeum of Clepsina, have brought to light a sequence of phases indicative of a longer and more complex history of urban occupation at the site than previously thought. The earliest stratigraphic evidence uncovered so far dates to the Late Iron Age, followed by an Orientalizing building with wall paintings, an important Archaic phase, and a large-scale renovation datable to the third century bc. Occupation was intense until the late first and early second century ad. Excavation and geophysical prospection have revealed a regular urban plan in the area between the centre of the city plateau and the sanctuary of Manganello. Research within the hypogaeum, particularly infrared imaging, has allowed for a better reading of wall paintings, drawings, and inscriptions, including two previously unknown texts.

At first glance, nine coins in the collection appear to be billon tetradrachms minted in Alexandria, Egypt, dating to the period of the Emperor Claudius (41–54 AD). On the obverse, there is a portrait of the Emperor Claudius, on the reverse his wife Messalina is holding their two children. A closer examination reveals, however, that each of these coins weighs substantially less than the majority of specimens belonging to the same issues. All of the coins appear to have silver-rich plated surfaces with copper-rich cores. Questions are raised, therefore, about their authenticity and methods of manufacture. The surfaces display a variety of corrosion products, some of which may also indicate past restoration treatments. A single coin was selected for time-of-flight secondary ion mass spectrometry (ToF-SIMS), X-ray photoelectron spectroscopy (XPS), and energy dispersive x-ray analysis (EDX) analyses to investigate the viability of utilizing these combined techniques in the study of ancient coins. In order to gain information on the composition and distribution of the various chemical components present at the surface and into the bulk, it is necessary to profile into the sample, which by definition is destructive. Thus, it is important to identify areas of interest for further analysis so that the amount of damage can be minimized while maximizing the information obtained. To accomplish this, large area imaging ToF-SIMS has been performed using the stage-raster option in an IonTOF ToF-SIMS V. Bi 3 þþ primary ions were used to map the surface and the positive secondary ion distribution images were obtained. Because of the varying topography of the sample, delayed onset of the generated secondary ion had to be used. Four areas were identified for further analysis, namely: (1) a Ag rich (minimal Cu content) area; (2) an area showing the presence of both Cu and Ag; (3) an area displaying visibly different surface characteristics, and finally, (4) a Cu rich (minimal Ag content) area. Chemical composition was obtained from these areas using XPS. To obtain further (nondestructive) depth information, EDX images were obtained, which would arise from a deeper sampling depth. In this case Ag was seen to be more dominant except for region (4). This implies a Cu enrichment at the surface as observed by the ToF-SIMS except for region (1). In this paper, the results of depth profiles in the bulk of the chosen areas are presented in order to ascertain the distribution of the various chemical components. This will allow future investigation on how the coins were manufactured. Published by the AVS.
