At www.thehindu.com/arts/books/article2913312.ece there is a book review of an edited collection of articles on the science and metal technology of the Indus Civilisation. This includes copper smelting, copper-bronze alloys, metal and mineral extrection etc (silver, lead, tine, iron, zinc, copper and gold). Harappa is dated between 2700-1900BC and therefore coincided with the Bronze Age. In fact, in conventional numbers bronze objects occur from 3000BC onwards (and the Harappa fits into this general world view). One of the articles argues that tin metallurge was developed in the Indus Civilisation and was disseminated by trade – particularly with Sumeria. In another discussion ancient glazing techniques are discussed – from the Early Chalcolithic to the demise of Harrapa (5000BC onwards). All this is in contrast to the view espoused by John Dayton in his 1980s book, 'Minerals, Metals, Glazing and Man' which is so beloved of deep revisionists.
At www.cam.ac.uk/research/news/archaeologists-discover-jordans-earliest-bui… which refers to a building found in the eastern Jordanian desert and dating back to 20,000 years ago. The region was once extensively occupied – at this time by hunter gatherers. It is a few huts belonging to them that have been found – in what was a green land with rivers and streams quite unlike the situation nowadays. The research is published in the online journal PLoS (15th Feb 2012).
