"Photography is a memory business," one of the Wise Men once told us.

Those words acted as a guide while we scanned hundreds of photos to select the baker's dozen appearing in this pictorial of the Christmas holiday season around the world this year.

Ranging in subject from Brazil's President Dilma Rousseff at a Christmas celebration in Sao Paulo to Sri Lankan Christmas decorations reflected by a pond in Colombo to a swimmer wearing a Christmas hat during the traditional Christmas bath in Monaco, these images struck us as especially memorable, at least among those shot in advance of Christmas Day itself.

Of course, the real test of their memorability will come next year, when we check to see whether we do in fact recall them. (The smart money says we will.)
