The Boston Globe's The Big Picture blog brings us a collection of photographs from all over the world on the occasion of the various festivals observing the Day of the Dead.
Starting with Halloween (although now secular), 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.
The above photograph is probably the most striking of the collection. It's of a man performing a Voodoo ritual during the Day of the Dead celebrations at the national cemetery in Port-au-Prince, Haiti.
