Final answer:
Sailors never come to Brobdingnag because it is a fictional land from 'Gulliver's Travels' that is difficult to reach, existing as a literary device rather than a real location.
Step-by-step explanation:
The question asks why sailors never come to Brobdingnag, but to answer this, we need to consider the context in which Brobdingnag is mentioned. Brobdingnag is a fictional land from Jonathan Swift's satirical novel 'Gulliver's Travels', where everything is of enormous size. The phrase itself in the question seems to be metaphorical or part of a literary discussion.
Sailors do not come to Brobdingnag because it is an imaginary location created as a literary device to explore human nature and society from a different perspective. In the context of the novel, it is depicted as being very difficult to reach due to its secluded and hidden nature, thus explaining why sailors, in the realm of the story, don't often come there. However, when discussing literature or metaphorical journeys, the reasons for not reaching Brobdingnag could be interpreted in various symbolic or thematic ways.
