Analysis of Sonnet LXV: Known in Vain

As two whose love, first foolish, widening scope,
Knows suddenly, to music high and soft,
The Holy of holies; who because they scoff'd
Are now amazed with shame, nor dare to cope
With the whole truth aloud, lest heaven should ope;
Yet, at their meetings, laugh not as they laugh'd
In speech; nor speak, at length; but sitting oft
Together, within hopeless sight of hope
For hours are silent:—So it happeneth
When Work and Will awake too late, to gaze
After their life sailed by, and hold their breath.
Ah! who shall dare to search through what sad maze
Thenceforth their incommunicable ways
Follow the desultory feet of Death?
