On Phoenician steles, you regularly find generic blossoms that don’t seem to depict any particular flower. These seem to be instances of non-spooky puns like they were common in all religions before spookery: Semitic פרחprḥ means “flower”, but also “flying away”, and by derivation “passing away”. That’s why these blossoms are found on gravestones. Modern-day spooks showed them in a the film Annibale, though I’m not sure if they had a special reason.
