The child who vanished into a tree
The account begins with a sage. In the version Incredible India gives from the temple's palm-leaf records, the founder of the shrine is Divakara Muni Vilwamangalam.
Vishnu appears before him in the form of an orphaned child, and the sage takes the boy in and shelters him.
One day the sage loses his temper and scolds the boy. The child leaves at once and disappears into the forest. Vilwamangalam goes after him. He follows the trail to a cave, and the place where the chase ends is the site of present-day Thiruvananthapuram.
There the boy vanishes into a mahua tree. The tree falls, and as it lies on the ground it takes the form of Vishnu reclining on the thousand-hooded serpent — the image the temple is built around.
The story explains the most striking thing a visitor meets inside. The presiding deity here is not standing or seated but lying at full length on Anantha, the serpent, and the image is so long that it cannot be seen at once. Through three doors of the sanctum the devotee sees it in three parts: the head and chest, the hands, and the feet.
It also explains the city's name. Kerala Tourism records that Thiruvananthapuram is taken to mean the land of Sree Anantha Padmanabhaswamy — the lord who reclines on Anantha.
The image that stands in the sanctum today is not the fallen tree of the story. Incredible India records that King Anizham Thirunal Marthanda Varma replaced the old idol with one made of 12,008 shaligram stones and herbal compound known as katu-sharkara, eighteen feet long, during his rebuilding of the sanctuary.
The legend's details beyond this outline — the sage's exact words, the form of the cave, the route of the chase — are not in the accounts we have found, and they are not filled in here.
