Question: What year did Saraswati die? Passage:In the 1980s, with the support of Swami Omanand Saraswati, he catalogued and evaluated metallic artefacts of the so-called Copper Hoard Culture by means of European methods and models for the first time, whereby numerous finds came to light especially in the Kanya Gurukul in Narela/Haryana. These artefacts appear to be non-functional objects, probably used in rituals or simply deposited in hoards, to judge from a lack of use-wear. Far away in Odisha, Yule published a find from a metals period cemetery in Sankarjang which may be the earliest musical instrument in India. He documented the early historic fortress at Sisupalgarh by means of a laser scanner, ground penetrating radar and a hand-held GPS receiver. Together with Corinna Borchert, Yule uncovered illegal building development within this nationally protected Mauryan site. From 2001-2004 in India, Yule documented so-called mud forts and other archaeological sites for the first time, especially in Odisha along the Mahanadi and Chhattisgarh. Images of his work especially in Odisha appear in the image bank heidICON.
