 Syncretism also works the other way in Haitian Vodou and many Catholic saints have become loa in their own right, most notably Philomena, the archangel Michael, Jude the Apostle, and John the Baptist.In a ritual the loa are called down by the "houngan" (priest), "mambo" (priestess), or the "bokor" and the "caplata" (sorcerers and witches) to take part in the service, receive offerings, and grant requests.The loa arrive in the peristyle (ritual space) by mounting (possessing) a horse (ritualist) in Creole referred as "Chwal"—who is said to be "ridden".
