I’ve only just found out about this one: Gothic Spaces / Gothic Places at The Manchester Centre for Gothic Studies, England, on 25th October 2014. The academic symposium has an interesting opening paper about… “John Carter, the zealous defender of the Gothic architectural style in late eighteenth and early nineteenth-century British culture” and publisher of the 18th century The Gentleman’s Magazine. Another Carter to offer up as a possible inspiration for Lovecraft’s Carter, perhaps?
