Tom Stone's "Patmos" describes all the island's highpoints, from the medieval Monastery of St. John, justly famous for its library and beautiful view, and the medieval Monastery of the Apocalypse, containing the grotto where St. John received his revelations, to the multi-colored stones of Lambi in the north and the fine sand of Psiliamo in the south, extends his description to the small nearby islands of Lipsoi and Arkoi, and even tells the reader how to go on to Ephesus, in Turkey.
