As Hermes once took to his feathers light,
When lulled Argus, baffled, swoon'd and slept,
So on a Delphic reed, my-idle spright,
So play'd, so charm'd, so conquer'd, so bereft
The dragon-world of all its hundred eyes,
And seeing it asleep, so fled away,
Not to pure Ida with its snow-cold skies,
Nor unto Tempe, where Jove grieved a day,
But to that second circle of sad Hell,
Where in the gust, the whirlwind, and the flaw
Of rain and hail-stones, lovers need not tell
Their sorrows,—pale were the sweet lips I saw,
Pale were the lips I kiss'd, and fair the form
I floated with, about that melancholy storm.
1819.
