The Buddha has died, and one of his senior disciples who was not present at his deathbed has come to pay homage to the Buddha's body. The body is held in the sort of nearly cylindrical container used in Siam for depositing the bodies of royal persons before cremation. The Buddha's feet appear for the disciple to worship.
On the back a kneeling sage is shown with a golden figure of the Buddha standing on the top of his headdress. This is probably the sage who, in an episode soon after the birth of the Buddha-to-be, visits the royal court of the Buddha-to-be's father to see the famous baby. Normally a child old enough to greet such a person would do so with signs of respectful humility, but, according to a Thai Buddhist text, instead of paying reverence the baby "rose into the air and placed his beautiful feet on the head of the holy man."
