The "Moriones" are men and women in costumes and masks replicating the garb of biblical Imperial Roman soldiers as interpreted by locals.
Morions roam the streets in town from Holy Monday to Easter Sunday scaring the kids, or engaging in antics or surprises to draw attention.
The towns of Boac, Gasan, Santa Cruz, Buenavista and Mogpog in the island of Marinduque become one gigantic stage.
[3] Then at three o'clock on Good Friday afternoon, the Santo Sepulcro is observed, whereby old women exchange verses based on the Bible as they stand in wake of the dead Christ.
Another possible derivation is from the Spanish word "murió" (root verb:morir) meaning "(3rd person singular) died".
The origin of the festival is traced to Mogpog and the year 1887 when Dionisio Santiago, the parish priest of said town, organized it for the first time.
