Wazir Chand is explaining life 4,000 years ago.He points to the rocky mounds looming over a huddle of brick houses, a herd of black buffalo and a few stunted trees.The rising sun burns off a chill mist over the north-west Indian plains.A low rise was a fortification, Chand says, and a darker patch of red earth hides the site of an altar. Nimbly stepping around piles of buffalo dung, he points to a slight depression. This, apparently, was a pit that may have been a reservoir.
To the casual onlooker, Rakhigarhi is unimpressive. Yet the rubbish-strewn mounds and fields around and under this Indian village are set to deliver the answer to one of the deepest secrets of ancient times.Rakhigarhi is a key site in the Indus Valley civilisation, which ruled a more than 1m sq km swath of the Asian subcontinent during the bronze age and was as advanced and powerful as its better known contemporary counterparts in Egypt and Mesopotamia.
