The success of the early trials prompted Davy to travel to Naples to conduct further research on the Herculaneum papyri. Accompanied by his wife, they set off on 26 May 1818 to stay in Flanders where Davy was invited by the coal miners to speak. They then traveled to Carniola (now Slovenia) which proved to become 'his favourite Alpine retreat' before finally arriving in Italy. In Italy, they befriended Lord Byron in Rome and then went on to travel to Naples.
