Vampire skull of Venice, 16th century!

At the height of vampire phobia in medieval Europe, suspicious corpses were buried by pushing a ball into the open mouth of the body. Fearing that tens of thousands of corpses would become vampires in Europe, especially in the plague-stricken European lands, the measures taken by the rural Europeans against it were enormous. Holy water, garlic flowers, the cross, the wooden spear, I think are the most common.

 I thought the bricks in mouth were the most obscure of them all.
