In PS the name of Chinna Pazhuvettarayar is 'Kalandhaga Kandar'. What is the the name of Periya Pazhuvettarayar? This is not mentioned in PS as far as I know. What Chozha history says about it.
I thought his name was Kandan Maravan ! Not sure - need to refer Pazhuvoor Pudhaiyalgal by dr.R.Kalaikkovan in which he details the chronology. By the way, Kaalanthaka kandar is an imaginary character:-)
Yesterday, i was talking to Dr.Kalaikkovan regarding the Periya and Chinna pazhuvettaraiyars of PS.
He said there were three brothers from Pazhuvur served Chola kings during Sundara chola period. They were neither 'Dhanaadhigari' nor 'Dhalapathi' but just common people. And their names are also not 'Ambalavaanan' and 'Kaalanthaka kandar'. There won't be any mention about them in 'Pazhuvoor Pudhaiyalgal' since they were not the kings of Pazhuvur.
