It is likely that Poe died of rabies which somehow sounds appropriate.
I think he really died of poverty which was entirely possible in his time.
That is very possible. What blows my mind is how long ago he died. I’m using my cellphone so I cant look it up, but I believe he died something like 10 years before the Civil war even started. That is a looooooong ass time ago. For some reason it seems like he died somewhere in the early 20th century but he didn’t.
