Tensing Rodrigues has for quite a long time been publishing a series of articles in the Navhind Times called Konkanapurana. This is quite a detailed exposition on how Goa got populated from the earliest times. He uses a vast variety of sources to buttress his arguments. It appears that this series of articles will end up as a book, but even if for some reason this doesn't happen, the Konkanakhyan articles, although inconvenient to consult, will provide a good overview of the historical and geographical developments that resulted in the Goa of today. The latest article is called 'Peopling the Komkan Coast' (see the link above) whereas last week the controversial Parshuram was in the limelight. Tensing's writing can at times be a bit dense and difficult to read, sometimes because of the unfamiliarity of the subject to a lay reader; sometimes for trying to pack in too much information into individual sentences; and sometimes for silly reasons - for eg, in the latest article I took more than 10 minutes to realise that AMH meant 'anatomically modern humans' because he hadn't bothered to place the acronym AMH after the term when it first appeared. However for those interested in this area of study I'd highly recommend the Konkanapurana articles. Best, Augusto
