Iconography
Aravan is always worshipped in temples in the form of his severed head. He is usually depicted with a moustache, pronounced eyes and large ears. Typically, he also wears a conical crown, a Vaishnava tilak mark on his forehead and earrings. Aravan is often depicted with a cobra hood over his crown, cobra heads sprouting through the crown, or a snake emerging from behind the crown. Even the chief Koovagam icon features a serpent on Aravan's crown.
Another distinctive feature of Aravan's iconography is the presence of demonic canine teeth. Although the central Koovagam icon does not feature such demonic teeth, they are a regular feature of most Draupadi cult images, where Aravan's demonic features are emphasized.
Aravan-head icons are either painted or unpainted portable ones for processions; they are housed together in the temples of his shrines. Koovagam, Kothadai, Kothattai and Pillaiyarkuppam have icons painted with a red face and multi-coloured ornamentation. Unpainted black stone images of the Aravan-head are seen in Kothattai, Madhukarai and Pillaiyarkuppam.
Some paintings also depict the sacrifice of Aravan. In these scenes, he is often depicted bowing to Kali, while his head is about to be severed; or, as in one Sowcarpet painting, a self-decapitated Aravan holds both a sword and his own severed head, offering the latter to the goddess.
