Wari-Bateshwar Fort-City Open air Museum, Narsingdi.
Prof. SS Mostafizur Rahman believes that Wari-Bateshwar is the rich, well planned, ancient emporia (a commercial city) “Sounagora” mentioned by Greek geographer, astronomer, mathematician Ptolemy in his book Geographia. The other emporia mentioned in Ptolemy’s work include Arikamedu of India, Mantai of Sri Lanka, Kion Thom of Thailand. All of these were the most ancient civilizations in their respective regions, each was a river port, and all of them produced monochrome glass beads. The artifacts found at Wari-Bateshwar bear similarity with those found in the other emporia sites.
Mathematician Narayan Chandra Ghosh, a resident of Kolkata visited his birthplace of Satirpara-Narsingdi and explored Wari-Bateshwar on 30 June 2016 to collect detailed information about mathematical concepts used there. He has popularized the word ‘Folk Mathematics’ that he has found at Wari-Bateshwar also. He has written articles on Wari-Bateshwar in Daily Desher Katha (Published from Agartala), Chalojai published from Kolkata.
