The poet has used the tool of humor and irony in the poem. Humor refers to cognitive experiences which provoke laughter in a person. Irony refers to the strange aspect of a situation that is very different from what one expects. Some instances of humor and irony in the poem are: The decision of the king to hang the chief of the builders for constructing a low arch when his crown struck against it evokes laughter among the readers. It is an example of humor. The way the king got convinced that actually the labourers who constructed the arch were responsible is also humorous. The king wanted to hang the labourers but the labourers were able to defend themselves. This situation is humorous as it evokes laughter among the readers and ironic as the readers find that the labourers are able to shift the responsibility to the architect. Ironically, the architect is able to shift the responsibility to the king himself.
The selection of the wisest man who would give the verdict as to who was the real culprit evokes laughter and is, therefore, humorous. The old man ultimately blamed the arch and declared that the arch must be hanged. Ironically, one of the ministers pointed out that the gathering wanted a man to be hanged. As the noose fitted the king's neck, so, he was hanged. The choice of a successor is humorous as an idiot is consulted for selecting the successor. The idiot chooses a melon who becomes the symbolic head of the state.
