On Yuan Chwang's Travels in India, 629–645 A.D. v2.c26.s2.30

Guesses as to the exact position of P'i-sho-ka (? = Vīśoka) (I, 373) and Kāśapura must also be unsatisfactory at present; but, after renewed study of the question, I should not be surprised, if the ancient site Nimkhār or Nimsār, 20 miles S. of Sītāpur, turned out to be P'i-sho-ka. If this be so, Kāśapura would be somewhere in the Unāo District. The country is full of old sites; and some lucky discovery is needed to give precision to topographical guesses, which alone can never solve the problem.¹
