From the New York Times (March 26, 2020):
I have seen Naples from his vantage of a ship anchored offshore — one of the most sublime locations in the world, that sweep of coast stacked with apricot, carmine, azure and rose villas; the blue, blue U of the harbor; the emphatic Vesuvius anchoring the view.

In October of 1820, typhus raged in Naples. With his artist friend, Joseph Severn, the British poet John Keats rocked in the city’s harbor for 10 days, not nearly the quaranta giorni — 40 days — that give us our word quarantine.
Before this journey, Keats always felt intense melancholy. In “On Seeing the Elgin Marbles for the First Time,” he wrote “… mortality / Weighs heavily on me like unwilling sleep.” (And in the smooth pentameter of “Ode to a Nightingale”: “I have been half in love with easeful death.”) Not a holiday, this voyage out of England was a desperate trip to the sunny climate of Italy. His cough had grown steadily worse. Since the morning he’d seen a splotch of blood on his pillow, he knew he had little chance of surviving the consumption that had invaded his lungs. His last-ditch: Go to Rome. Meanwhile, exile at sea.
Prometheus Unbound is a four-act lyrical drama by Percy Bysshe Shelley, first published in 1820. It is concerned with the torments of the Greek mythological figure Prometheus, who defies the gods and gives fire to humanity, for which he is subjected to eternal punishment and suffering at the hands of Zeus. It is inspired by the classical Prometheia, a trilogy of plays attributed to Aeschylus. Shelley’s play concerns Prometheus’ release from captivity, but unlike Aeschylus’ version, there is no reconciliation between Prometheus and Jupiter (Zeus). Instead, Jupiter is abandoned by his supportive elements and falls from power, which allows Prometheus to be released.
