'Fair Isabel, poor simple Isabel!
Lorenzo, a young palmer in Love's eye!
They could not in the self-same mansion dwell
Without some stir of heart, some malady;
They could not sit at meals but feel how well
It soothed each to be the other by;
They could not, sure, beneath the same roof sleep
But to each other dream, and nightly weep.'
