You can't talk about DRACULA without talking about John Polidori's THE VAMPYRE, which came out of events in the summer of 1816.
Wikipedia's article - http://en.wikipedia.org/wiki/
New England's reaction to 1816 can be found here:
My inner geologist has always wrangled cooperatively with my inner sociologist. One of the current frequently-cited topics in the media nowadays is the effect of climate change, and thus something like my little project here could hardly be more timely, in holding a mirror up to human reactions to weather then and human reactions to weather now.
Extended periods of such weather as we expect for the entire coming week led to a little wager among friends back in 1816. A thoughtful article on the subject, although it is focused on the Shelleys, can be found here:
FRANKENSTEIN by Mary Shelley gained lasting fame, but John Polidori's THE VAMPYRE, as forgotten as it may seem, made Bram Stoker's DRACULA possible.
I'm not going to post the whole text of Polidori's work here, but it would behoove those Gentle Readers who are joining me for Blog Stoker's DRACULA to bone up on it. [Pun intended.]
