The Stars and I

IMMENSE the stars are, and immense the sky,
And very, most exceeding small am I;
Sometimes I think, as through the night I lurch,
That I am like a tiny flea in church.

Yet other times I seem extremely big,
A kind of mammoth, or at least a pig;
Then, I conceive the stars as very small
Or else I do not see the stars at all.
