The volume presents very lively debates amongst great scholars of the old generation e.g., between D.C. Sircar and V.V. Mirashi on the spread of the Saka Era in South India, D.C. Sircar and R.C. Majumdar on the Harsha Era. All the research papers compiled in this volume from the now defunct Journal, Indian Historical Quarterly, (1928-1963) edited by N.N. Law create an impression that all the dates and eras in Indian History are mired in some controversy. But at the same time, they instil in us a sense of humility and gratitude for the painstaking efforts made by scholars of the last century to resolve these controversies. We are simply overwhelmed by their great erudition and originality. We hope, this volume will serve as an inspiration and a model for the future researchers.
