The Re-echo Club: as by Percy Bysshe Shelley (Purple Cow)

Hail to thee, blithe spirit!
Cow thou never wert;
But in life to cheer it
Playest thy full part
In purple lines of unpremeditated art.

The pale purple color
Melts around thy sight
Like a star, but duller,
In the broad daylight.
I'd see thee, but I would not be thee if I might.

We look before and after
At cattle as they browse;
Our most hearty laughter
Something sad must rouse.
Our sweetest songs are those that tell of Purple Cows.
