There are similar Christmas legends around the world. In some places, they believe the gifts are left by the three Magi who never did find their way home after meeting Jesus.
Another is an old woman who met the Magi and also wanted to visit the Christ Child, but delayed to finish her housecleaning. When she finally put a sack of toys on her back and set off, the Magi were long gone and she got hopelessly lost. Ever since then, she's been wandering the world looking for Jesus.
