Paul Theroux's The Pillars of Hercules: A Grand Tour of the Mediterranean ( 1995 ). His intention was to circle the Mediterranean, clockwise, from Gibralter to Ceuta. He appears to have had no distinct plan other than this, over 18 months; I marvel that he just takes me along with him as he bumbles along the coast. He is erudite, open-minded. He isn't drawn to ruins or to sights or sites. He talks to you, the reader, as his confidant.
I, however, would probably traipse here, being fond of ruins, if they are not tourist draw-cards. Above is an image of the theatre itself, taken from a little book I've found, Provincial Art: Southern Italy and the Islands, published in 1957 by the Italian State Tourist Office.
