The Worm in Its Masonry Tank

From D6.12, The Story of Haftvad and the Worm. It illustrates D6.12.59–66:

D6.12.59
When once again the worm outgrew its chest,They built a masonry tank at his behest.
D6.12.60
When stone and mortar warmed within the air,They placed the worm inside with gentle care.
D6.12.61
Each dawn the keeper hurried on his way,From Haftvad’s presence at the break of day.
D6.12.62
He made a great rice ration for its feed;The worm consumed it all to meet its need.
D6.12.63
Five years passed by; its neck and body spread,An elephant in bulk from tail to head.
D6.12.64
His daughter kept the creature at her side;Her father led its troops with martial pride.
D6.12.65
In Chinese silk they clothed the worm with heed,While rice and milk and honey met its need.
D6.12.66
The foolish man rejoiced in it the more;Haftvad, its chieftain, waited at its door.
