“Kaire ‘o polita apragopoleos”, “Hello, citizen of the land of idleness.” For the welcome sign on the entrance of his eccentric house in Capri, Colonel John Clay MacKowen had chosen ancient Greek and evoked the nickname "apragopolis", or "island of sweet doing nothing" with which the emperor Augustus loved to define Capri to which he was so attached. All clear references to his great passion for archaeology.
