The Romantic poets Keats, Shelley and Byron, with their classical education and love of ruins and decay, were mesmerised by Italy, and especially by Rome. Shelley wrote Prometheus Unbound in the massive ruins of the Roman Baths of Caracalla.
In 1845, long after the death of both Keats and Shelley, Joseph Severn painted Shelley Composing Prometheus Unbound in the Baths of Caracalla.
You can still visit these sombre ruins today, though they have been tidied up a little since Shelley’s time. Now they are surrounded by trimmed lawns instead of overgrown weeds.
