In Homer's Odyssey (8th c. BC), while in the underworld Odysseus attempts to hug his mother Anticlea but is unable to do so.
Thrice I sprang towards her, and my heart bade me clasp her, and thrice she flitted from my arms like a shadow or a dream..... “‘My mother, why dost thou not stay for me, who am eager to clasp thee, that even in the house of Hades we two may cast our arms each about the other.... Is this but a phantom (ghost) that august Persephone has sent me, that I may lament and groan the more?

Ancient Romans used "umbrae" (shadows) to refer to ghostly spirits, which for me invokes the figures on the wall of Plato's cave
Interesting regardless though.
One should not that Homers dialect is arcane from the start of the Greek golden age, so translation is always going to be interesting.
