Identifying a ghost in Greek literature and distinguishing it from what we might call a delusion or a supernatural entity can sometimes pose difficulties: *Homer tends to use the term psyche to describe his spirits, but we also find skia. In later writers, eidolon is used (Hdt. 5.92.η and Pl. Leg. 959b of the corpse), which can also mean a phantom of the mind, or even just a likeness. Later still, *daimōn, alone, or combined with other words to evoke particular forms of demon (see below) appears. Other terms (which will appear throughout the entry) evoked the particular ways in which individuals died and became ghosts. This entry will focus on appearances in the mortal realm of spirits connected to a death, indicating where there are any ambiguities of spectral terminology. As the move from psyche to daimōn might suggest, there seems to be a gradual development in the strength, substance and presence of ghosts in the ancient world; while living mortals seem, in turn, to find increasingly sophisticated ways to manipulate their spectral visitors and their needs for their own ends.
