Vampire Information...

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, reputedly the first reference to vampires in English literature
