Egyptian Imperial Porphyry

I am preparing a monograph on Imperial Red Porphyry from the Egyptian quarries with a chapter dedicated to the quarries, its extraction and its transportation. A section will be devoted to the political, religious and symbolic value of the purple stone and of the Lapis Porphyrites. Another chapter will be dedicated to the history and development of this material for portraiture in sculpture. Finally, there will be a detailed catalogue including more than one thousand images of all the artistic and architectural artefacts made in this magical marble, each accompanied by a full catalogued entry.
