This volume does exactly what it says in the title: provide an account of the Hellenistic, Roman and medieval glass from the site of Cosa in Southern Tuscany, Italy. This much awaited publication of the glass from Cosa was made possible through the initial labour of G. and, after his death in 2004, the efforts of J. Price and R.T. Scott and their colleagues.

The volume itself takes the form of a rather typical artefact catalogue, beginning with a description of Cosa and the material (pp. 1–6), the dating (pp. 7–16) and the classification and description of the glass (pp. 17–26). The bulk of the book is formed by its sizeable and wide-ranging catalogue (pp. 27–214). Concordances (pp. 215–26), a glossary (pp. 227–30), a short Cosa bibliography (pp. 231–4) and the short titles of works mentioned in the text (pp. 235–47) add to its utility and clarity. The accompanying 37 black-and-white plates are well drawn and clear, although one cannot help lament (along with the editor and Price in the preface [p. xiv]) the loss of B. Bini's original photographs. The material from Cosa includes ‘Hellenistic’/Republican and Early-Imperial period material, so that there is glass of just about every colour imaginable, including patterned and polychromatic vessels and objects. While it is unrealistic to expect the material from one site to constitute a representative and exhaustive reference collection for ‘Roman glass’ in the broadest sense, the material published in this volume comes close.

The catalogue is particularly useful as it demonstrates a long period of glass use, from the middle of the second century bce to the first half of the fifth century ce, although there is also evidence for activity in Cosa in the sixth century. Additionally, the catalogue mentions glass from the thirteenth and early fourteenth centuries, from a period of re-occupation at Cosa. Of the more than 15,000 fragments excavated and studied by G., most were Roman in date, and the bulk came from undecorated free-blown vessels, with fewer scraps of decorated blown, mould-blown and cast vessels.

While this volume is useful in demonstrating the continuity of glass use at Cosa, and as a reference work, it does not engage in the sorts of detailed intra-site analyses that more recent publications of glass and other artefacts do. Although the volume was published in late 2017, it superficially seems rooted in the methodology of the immediate past, but this is an understandable relic of the delay in the completion of this work. This volume is a new key reference work for scholars of ancient and medieval glass, and for anyone interested in the socio-economy of historic Cosa and the ager Cosanus more broadly.
