The Thrilling Adventures of Lovelace and Babbage
The Mysterious Figure in the prologue of Vampire Poets is Lord Byron himself.
Just the title is enough in and of itself. Who was the inspiration for the modern vampire? Who is the poet whose memory hangs over Lovelace? Granted, he's dead, but he does say 'alas, across the Styx I'm drawn,' at one point. And he's a vampire. And the time-space continuum in this comic is messed up. Also, there is just something indefinably Byronish about that prologue, to this troper's mind.
