From October 31st through November 2nd, a number of festivals, holidays and solemnities take place, all loosely related and revolving around remembrance of the dead. Halloween, Samhain, All Saints' Day, All Souls' Day, the Day of the Dead and other festivals trace their origins back to Celtic, Aztec, Roman and Christian traditions. Halloween is largely a secular observation these days, All Souls and All Saints remain mainly Catholic observations, and the Day of the Dead is still largely a Latin American tradition, its roots in Mexico's Aztec heritage. Collected here are photographs over the past week from the varied observations of the Days of the Dead around the world.
