Still, the idea that the spirit of a dead person or animal could return to the land of the living was present as far back as the ancient world, according to Morton, the author of Ghosts.
In the Mesopotamian text Epic of Gilgamesh, Gilgamesh’s late friend Enkidu appears as a specter and recounts to Gilgamesh his experience in the underworld. One section of Homer’s Odyssey describes Odysseus traveling through the underworld and encountering the ghost of his mother, Anticlea.
Ghosts take a turn for the malevolent
Over time, the word “ghost” does some shape-shifting, both in its meaning and in how it’s spelled.
The Old English gast and Middle English gost picked up a silent “h” centuries later thanks to the influence of Flemish typesetters, said Zafarris. When William Caxton introduced the printing press to England in 1476, the Bruges-trained printer also brought with him compositors from the Low Countries, who modified some English words using Flemish spellings.
“That also happened to words that are related to ghosts, like ‘aghast’ and ‘ghastly,'” Zafarris said, “and you’ll notice that those also have that breathiness to them, things make you gasp.”
