Unless, governor, inspector, visitor,
This map becomes their window and these windows
That shut upon their lives like catacombs.
Break O break open till they break the town
And show the children to green fields, and make their world
Run azure on gold sands, and let their tongues
Run naked into books the white and green leaves open
History theirs whose language is the sun.
Name the literary device used in ‘like catacombs’.
