Did we discuss about the king who asked Kanikannan to praise him? I don't know the century of Thirumazhisai Azhvaar. But I remember hearing the city of the king was Uraiyur, so is he a Chola?
The site also gives detailed information about each Divyadesam and group it by location. Very informative.
Thirumazhisai Azhwar, chronologically is said to have lived before Nammazhwar, who some historians hail as the contemporary of Vijayalaya Chozha, the first of the mediveal Cholas. So he must have lived some where in the fag end of 9th century.
But the king was not a Chola, but a king from Kanchi. Given the fact that Pallavas ruled from Kanchi before Vijayalaya revived the Cholas, this king could well be a Pallava. Need not be Aparajitha, the last of Pallavas, as there is no account regarding the time when this incident happened. So it could be Aparajitha or one or two Kings prior to him.
