The title is Latin and means “Love of the World”.
The poem initially traces the beginning of a loving relationship, with its sense of ease and joy. But this pleasure is interrupted by ‘blackest clouds’, symbolising and fear and doubts, and the awareness that one’s actions can have dire consequences....
"O where are you going with your love-locks flowing,
On the west wind blowing along this valley track?"
"The downhill path is easy, come with me an it please ye,
We shall escape the uphill by never turning back."
So they two went together in glowing August weather,
The honey-breathing heather lay to their left and right;
And dear she was to doat on, her swift feet seemed to float on
The air like soft twin pigeons too sportive to alight.
"Oh, what is that in heaven where grey cloud-flakes are seven,
Where blackest clouds hang riven just at the rainy skirt?"
"Oh, that's a meteor sent us, a message dumb, portentous,
An undeciphered solemn signal of help or hurt."
"Oh, what is that glides quickly where velvet flowers grow thickly,
Their scent comes rich and sickly?"--"A scaled and hooded worm."
"Oh, what's that in the hollow, so pale I quake to follow?"
"Oh, that's a thin dead body which waits the eternal term."
"Turn again, O my sweetest,--turn again, false and fleetest:
This beaten way thou beatest I fear is hell's own track."
"Nay, too steep for hill mounting; nay, too late for cost counting:
This downhill path is easy, but there's no turning back."
