In the Haryana region had developed many urban centres when Panini wrote his Sanskrit Grammar book. He in Astadhayi, has mentioned the following 9 town names from the region included in modern Haryana state:
1. Sonaprastha : Modern Sonipat
2. Roni : Modern Rodi in Hisar District.
3.Kapisthala: Modern Kaithal.
4.Sairisaka : Modern Sirsa
5. Srughana: Ancient capital of the Punjab; Modern Sugh which covered the Area inhabited now by Jagadhri Town, Buria, Chaneti, Dayalgarh, Sugh and Amadlpur villages.
6. Yugandhara : Modern Jagadhri.
7. Gaudapura is perhaps old name of Gurgaon.
8. Tausayana is modern Tohana, and
9. Kalakuta was probably Kalaka in the Panchkula district.
But it is surprising to note that in the list of these towns, Sthaneswar or Kurukshetra has found no mention !
