The Plague Bird

The crow has been always seen as a symbol of death by many cultures, during many centuries. I personally love them, they have that mistery aura, majestic looking....just as Plague Doctors, with their long-beaked masks and black robes. Here's my raven, wearing one of those masks, resting upon an old medical book. Is it the pet of some alchemist? Is he good, is he evil? I don't even know.
