On swift tail flaming
From storm and south
He comes, pale vampire,
Mouth to my mouth.
-James Joyce, "Ulysses"

But first, on earth as Vampire sent,
Thy corpse shall from the tomb be rent:
Then ghastly haunt thy native place,
And suck the blood of all thy race;
There from thy daughter, sister, wife,
At midnight drain the stream of life;
Yet loathe the banquet which perforce
Must feed thy livid living corpse.
Shall know the demon for their sire,
At cursing thee, thou cursing them,
Thy flowers are withered on the stem.

-Lord Byron, The Glamour, 1813

Vampires are lucky: they can feed on others.
We gotta eat away at ourselves.
We gotta eat our legs, so that we got the energy to walk.
We gotta come so that we can go.
We gotta suck ourselves off.
We gotta eat away at ourselves
'til there's nothing left but appetite.

-From 'The Bad Lieutenant'
