It is intriguing as to why no native account/cultural memory of the hedge exists, especially since it spanned various states. On the other hand though, it also reminds me of a recent Twitter thread [1] about India: "Ever wondered why the Harappan Civilization had to be "discovered" in the 1920 and there is no cultural memory of it and no mention in our ancient literature? No pilgrimage circuits involving Dholavira, Lothal or Mohenjo-daro? The Buddha had to be 'discovered' too. And Ashoka."
