I found these truly lovely images on Mashable. They are ‘colour’ photos of Rome dating from c. 1890, sourced from the Library of Congress. These were taken seventy years after Keats was in Rome, but it still feels like a glimpse into the world that he would have recognised. Joseph Severn would have known this Rome, as he died only ten or eleven years before.
I’ve copied the two most relevant images here (with great respect, but without permission) and you can see the rest via the link below.
A lovely article that traces – in great detail! – Keats’ trip on the mail coach from London to Southampton on 14-15 April 1817. (And I’m delighted to see that this was written in the context of preparing a new collection of essays on the theme of “Keats and place”.)
