How do you stop a vampire?

You stick a brick in its mouth, of course. Or you bury its head between its legs. Or perhaps you skewer its corpse with an iron rod. Archaeological excavations across Europe -- from Poland to Italy to Ireland -- reveal human remains buried in atypical fashions, and these abberant burials shed suggestive light on different medieval and early modern communities' beliefs in the not-so-normal dead. And they might provide some useful tricks for surviving the Zombie Apocalype.
(BTW, as I understand it vampires per se weren't a part of western European folklore until the late fifteenth or early sixteenth centuries. You do find references to other kinds of revenants, however, in medieval literature from at least the 10th century.)
