Building between the Two Rivers: An introduction to the building archaeology of ancient Mesopotamia aims to introduce university students and scholars of Neer Eastern archaeology to the 'building archaeology' methods as applied to the context of Ancient Mesopotamia. It helps the reader understand the principles underlying this discipline, which deals with the registration and analysis of all the building materials and techniques involved in the assembly and erection of constructions and the realise what knowledge and skills are needed, beyond those that are specific to archaeologists. The in-depth registration and analysis of building materials and techniques require professional skills and experience, which cannot be achieved with only a standard university training in archaeology. However, archaeologists need to know the basics of the classification of building materials, their physical properties, the main techniques of their finishing, as well as the basic principles of statics. They should also be able to let architects understand how to better tune the registration of data to ensure a fruitful archaeological interpretation. Due to the introductory nature of the book, contents are organised in didactic chapters, trying to cover all the main topics and displaying them by means of selected examples. Particular attention is given to the methods of the 'stratigraphic reading', which are discussed in a dedicated appendix authored by Piero Gilento. A thematic bibliography and a technical glossary complete the book, helping readers enhance their understanding of the subject.
