The monument of Episkopi on Sikinos, one of the smallest Cycladic islands, is a heroon, dating from the 3rd century. Because of its conversion to a Byzantine church, it was continuously used and has therefore survived nearly intact. Its ancient structure, combined with interventions from several historical periods, offers an incomparable palimpsest of archaeological periods that is rarely preserved in ancient monuments.The most important find was the hermetically sealed deviant burial of a woman of high rank, named ‘Neiko’, which was dated to the 2nd century.
