43i of Ngha's forces before theinvasion of Candrabhnu. Secondly, the C!fllavaisa judiciously avoids any mention ofthe forty-year occupation, although this work is later than the P'jvaliya and its accouut ofthe campaign against the forces of )gha is remarkably similar to that ofthe P11jvaliya. This, too, casts some doubt on the validity ofthe Pjvaliya statement. It is, therefore, possible that the figure 'forty' inthe statement ofthe P11jva1iya is a mistake. It may also be possible that MAgha was ousted from Polonnaruva before l2k7 but his forces were not completely routed till 1255. The forty-year occupation may refer to the presence ofthe enemy inthe northern parts ofCeylonand not to MAgha's rule in Polonnaruva. Parana'uitana's second argument in favour of 1255 as the date of MAgha's defeat is that If we take that Polonnaru andthe Rjaraftha were recovered by Parkramabhu before l2k7, in which year theinvasion of Candrabhnu was repulsed, he had no enemies to contend with until the second invasion of Cand.rabbnu, which, as will be shown later, occurred in or about 1260, andthe P4ya invasions, the first of which was in or about 125k. He was, therefore4 free on this supposition, to realise his ambition of being crowxied at Polonnaru, andof restoring the Tooth Relic to its ancient shrine at that city. But, for about ten or fifteen years after the first defeat of Candrabbnu, Parkramabhu paid no attention toolonnaru. All his religious and other activities during these years were inthe MAyraf a, or inthe south-western or central districts ofthe Island. The reason for this must have been that Polonnarurwas still inthe hands ofthe enemy, who abandoned it after an occupation of forty years, as stated by the PUjva1!, in 1255. 1 1. U.C.H.C., I, pt.2, p. 621.
43? This is not quite convincing. During the whole period of his r reign, Parkramabihu had to contend with a number of enemies. First ?1gha, then Candrabhnu and possibly the Pyas as we shall see later, gave constant trouble to the Sinhalese ruler. If one asks why Parkramabhu failed to hold his coronation at Polonnaruva between 12k7 and 125k when there were no foreign invasions, one may also ask why he failed to achieve that between 1255 and 1260 when, according to Paranavitana, Parkramabhu bad freed Polonnaruva ofthe enemy. The date of Candrabhtnu's second invasion is not definitely known to be 1260. Some place it in 1262 and some others later on If we accept 1262, the time lapse between 12k7 and 125k is almost the same as that between 1255 and 1262. If during the seven-year period between 12k7 and 125k Parkramabhu was pnevented from realising his ambition by !gha'a presence in Polonnaruva, what prevented him from achieving his aim during the seven-year period from 1255 and b.CAtler 1262, whenIgha o2, any other enemy was at Polonnaruva I It is not possible , therefore, to argue that )gha was ruling at Poloxinaruva till 1255 on the basis that Parkramabhu failed to hold hid coronation in that city before 1255. As we shall aee later on, whether )Zgha was defeated in 1255 or before 12117, what is important is that the Sinhalese rulers could not get 1. A.Liyanagmge, 2•
