 As noted by T.W.Rhys Davids, Wynne points out the pali texts depict a pre-Asokan north India and he also cites KR Norman who argues that they show no Sinhalese prakrit additions.Reviewing the literature by figures such as Frauwallner, Wynne argues that the pali suttas reached Sri Lanka by 250 BCE and that they preserved certain details about fifth century north India (such as that Uddaka Ramaputta lived near Rajagrha).
