I just saw this on the Oxbow books website, the book is on offer. It was £82.50 and is now £19.95 which is pretty good. I have not heard any reviews but one piece that caught my eye was this,
'Whilst there is a description of the mosaics, their technique and style, the overwhelming emphasis is on investigating aspects of production and technology, such as the laying of the floor, identifying the different hands involved in the production of the mosaic floor, the likely source of the stone used and the glass-making techniques employed'.
If anyone has a copy then please do let us know what you think of it.
