Deities of these three temples were sculpted by the same person.

Sikkal is also closely associated with Ettikkudi and Enkan through the legend of a sculptor who carved the three Murugan idols of Sikkal, Engan and Ettukkudi are exquisite and carved by the same Shilpi. When he carved the idol with every detail of the 6 faces of the lord with separate ear ring holes, hands separate weapons and balanced on the single leg of the peacock with space below the claw. The king wanted to prevent any other replica so he obtained the thumbs of the Shilpi as a guarantee. Even with this lack of thumbs the Shilpi sculpted a replica at Ettukkudi for this the king removed the eyes of the sculptor. The Sculptor was directed by a divine voice to sculpt a more detailed Singaravelan at Engan after which he received both his thumbs and vision.
