What is Seven Sleepers’ Den?

What do you know about the seven sleepers’ den?

Ans: Seven Sleepers’ Den indicates the cave of the seven devoted Christian Brothers of Ephesus who slept in a cave for about two hundred years to escape the death sentence by the king. It is an example of conceit, allusion, and superficially metaphor. We get this reference in The Good Morrow by John Donne. Here the poet has used the seven sleepers’ den to compare the innocence of the lovers with that of the seven brothers.
