The 25 July is St Christopher's day. He is the patron saint of travelling and travellers, mariners, ferrymen and also athletes.
There are several legends about him including this popular one:
One dark and stormy night, a child came to Christopher and asked to be carried across the river. Christopher put the child on his shoulders and waded into the wild river. He found the child unusually heavy and had to struggle desperately to reach the other side. When he reached the othe other side the child told him that he was the Christ for and that he had carried the weight of the whole world on his shoulder.
The literal meaning of the name 'Christopher is Christ-bearer.
Some people where St Christophers pendants, or give them to friends and relatives, when they are going on a long journey.
