Then stirs the feeling infinite, so felt
In solitude, where we are LEAST alone;
A truth, which through our being then doth melt,
And purifies from self: it is a tone,
The soul and source of music, which makes known
Eternal harmony, and sheds a charm,
Like to the fabled Cytherea's zone,
Binding all things with beauty;--'twould disarm
The spectre Death, had he           power to harm.
