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. Appearing frequently on funerary art, psychopomps have been depicted at different times and in different cultures as anthropomorphic entities, horses, deer, dogs, whip-poor-wills, ravens, crows, owls, sparrows and cuckoos. When seen as birds, they are often seen in huge masses, waiting outside the home of the dying.
