Upon Appleton House, How did the nun try and convince Isabella to become a nun?

The speaker now changes to the head nun at Appleton, who speaks her words directly to Isabella in an attempt to persuade her to devote her life to the cloister. The nunnery at Appleton is figured as a secure and private space, whose “bars inclose that wider den / Of those wild creatures, called men.” The nuns live their lives like Amazonian female warriors of virtue, guarding their “chaste lamps” and devoting themselves to “incessant prayer.” The speaker goes on, however, to suggest that the cloister is in fact a place of private pleasures among the nuns, where Isabella “may lie chaste in bed” with other nuns, “All night embracing arm in arm, / Like crystal pure with cotton warm.” These implications of female eroticism and sex amongst the nuns prepare readers for the heroic entry of William Fairfax, who rescues Isabella from the false religion of the cloister, marries her, and eventually establishes the right of the Fairfaxes to take over the estate at Appleton.
