 For some, Palagruža is associated with the Homeric hero Diomedes, King of Argos, who is reputed to be buried here, though it is hard to imagine where.Speculation is fueled by the discovery of a painted 6th-century BC Greek potsherd with the name "Diomed[es]" on it (see image on Adriatica), making a shrine by the Cult of Diomedes on Palagruža seem plausible.Authentic archaeological finds of the Neolithic, Greek, Roman, and early medieval periods have been recorded.
