Sibylle de Cumes
Mary Shelley states in the introduction that in 1818 she discovered, in the Sibyl's cave near Naples, a collection of prophetic writings painted on leaves by the Cumaean Sibyl. She has edited these writings into the current narrative, the first-person narrative of a man living at the end of the 21st century, commencing in 2073 and concluding in 2100. Despite the chronological setting, the world of "The Last Man" appears to be relatively similar to the era in which it was written.
