sentences:  Gajabahu I lived in the early part of the second century A.D. and Gajabahu II in the twelfth century.If the latter was king referred to in the Cilappathikaram, Karikala Chola, the grandfather of the Gajabahu contemporary, Imaya Varamban should have lived in the eleventh or twelfth century A.D.But in many Tamil poems and inscriptions on copper plates recording the grants of Chola kings who lived in the tenth and the eleventh centuries, Karikala Chola I is described as one of the earliest and most remote ancestors of the Chola kings then reigning.
