Methought I lay
Watching the zenith, where the milky way
Among the stars in virgin splendour pours; 580
And travelling my eye, until the doors
Of heaven appear'd to open for my flight,
I became loth and fearful to alight
From such high soaring by a           glance:
So kept me stedfast in that airy trance,
Spreading imaginary pinions wide.
