The Re-echo Club: as by Algernon Swinburne (Purple Cow)

Oh, Cow of rare rapturous vision,
Oh, purple, impalpable Cow,
Do you browse in a Dream Field Elysian,
Are you purpling pleasantly now?
By the side of wan waves do you languish?
Or in the lithe lush of the grove?
While vainly I search in my anguish,
O Bovine of mauve!

Despair in my bosom is sighing,
Hope's star has sunk sadly to rest;
Though cows of rare sorts I am buying,
Not one breathes a balm to my breast.
Oh, rapturous rose-crowned occasion,
When I such a glory might see!
But a cow of a purple persuasion
I never would be.
