There is a story of Martin Luther walking in the woods in Latvia and creating the first Christmas tree in 1510. Whether or not it is true, the first Christmas tree recorded was in the town square of Riga, Latvia - not Germany. In Argentina Christmas trees are decorated on the Feast of the Immaculate Conception (8 December). Globos are lightweight paper decorations with a light inside that many Europeans release into the sky after midnight on Christmas Eve - hundreds of tiny God-lights in the sky. The Nativity crib scene was first made popular in Italy by St Francis of Assisi in 1223, a year after he had visited Bethlehem and seen where it is believed that Jesus was born. Many Italian families have Nativity cribs in their homes. Croatian Christmas preparations begin on St Catherine's day (25 November) with an Advent wreath of straw and evergreen twigs holding four candles representing hope, peace, joy, and love.
