Cease then, my song, cease the unequal lay.

The personified Fancy is in direct conversation with Imagination, and it seems to be the fancy of the speaker. The speaker seems to fall under the sway of some kind of love object, and is fettered by this attachment. Though the ominous force of Winter tries to hold the speaker's Fancy back, Imagination helps the speaker to imagine spring, and the flowering of love and possibility. Indeed, the "subject-passions" are ruled by Imagination, and Imagination has the power to create anything in this poem. But Winter, which symbolizes reality, must eventually materialize, and though the speaker's Fancy may try to break free of the shackles placed on her by love, as the sun rises, and Aurora rises with it, the speaker must turn away from the sun rise, from the mountain, and rejoin Winter.

So, even though Imagination allows hearts and minds to wander, eventually reality must set in, and reality cannot let us—the reader or the speaker—live wholly in the imagination.

The fetters described in this poem also symbolize slavery, and the limitations placed on the enslaved. Indeed, though the Fancy of the speaker wishes to ascend from the shackles placed onto her, and rise to Aurora, the reality of winter forbids this. Imagination has its limits in this poem, and ultimately Winter—reality—must step in and limit the possibilities of the Imagination. Since Winter forbids the speaker to "aspire," it seems like the speaker cannot rise, breathe, or imagine too much. Indeed, reality seems to place shackles that even Imagination cannot surpass. By ending the poem asking to "cease the unequal lay," the speaker suggests that there is an unequal relationship between reality and imagination, and implores this inequality to cease.

The relationship between the speaker and Winter is also an allegory for enslavement within this poem, as imagination is stopped by Winter's control, and the speaker must listen to Winter's demands to turn away from Aurora and the mountains against their wishes.
