He is referred to in the Rajarajeshwaram Temple inscription in which he is referred to as the husband of Kundavai Pirāttiyār.

In popular culture
Vandhiyadevan is one of the key characters of the novel Ponniyin Selvan. The author Kalki Krishnamurthy depicts him as a brave, adventurous and sarcastic warrior/prince, who later becomes the Commander for Southern Troops under the reign of Uttama Chola. He was a bodyguard and close friend of Aditha Karikalan in Kanchi who sends him as a messenger to Parantaka II in Thanjavur to invite him to the newly built golden palace in Kanchi and also as a trustful guard for Kundavai in Pazhayarai. His unplanned and hasteful acts put himself and others in danger but comes out of them by trickery and luck. He is the lover of Princess Kundavai. He is loved one-sidedly by Manimekalai, the sister of Kandamaran. The author introduces most of the characters to the audience through him.

A life sized statue depicting Vallavaraiyan controlling a horse was erected in Chennai during the first tenure of Mr. Karunanidhi as Chief Minister, near Gemini Flyover in Mount Road as an honour to Vallavaraiyan. Interestingly, this also coincided with the banning of horse races by the government of Tamil Nadu.
