Psychopomps (from the Greek word ψυχοπομπός - psuchopompos, literally meaning the "guide of souls") are creatures, spirits, angels, or deities in many religions whose responsibility is to escort newly deceased souls from Earth to the afterlife. Their role is not to judge the deceased, but simply to provide safe passage. Frequently depicted on funerary art, psychopomps have been associated at different times and in different cultures with horses, whip-poor-wills, ravens, dogs, crows, owls, sparrows, cuckoos, and harts. When seen as birds, they are often seen in huge masses, waiting outside the home of the dying.
