Among the royal titles used by the early Sinhalese kings there are two which, as royal titles, were not adopted by any of the dynasties known to us in India, and were therefore peculiar to Ceylon. An investigation into the history of these two titles is likely to throw some light on the origin of kingship in ancient Ceylon, and I therefore propose in this paper to pursue this line of study so far as the material available at present allows us to do so. The conclusions at which I have arrived by a study of the available data on this may not, in the present state of our knowledge, be taken as definitely established; but they might, nevertheless, be worthy of consideration by scholars interested in the early history of the Sinhalese people.
