As for good fortune, it is brought only by a horseshoe that has been found instead of bought and it must have been already worn by a horse. Nailed to the door or threshold of a house it will bring money and protect the household from evil forces and thieves; nailed to the door of the barn it will make sure that cattle grow well and bring profit. There is no unanimity regarding the way the horseshoe should be fastened to the door: with the ends facing up to prevent the good fortune from flowing out or down to facilitate the flow of good fortune into the house. Both views are present in the Latvian tradition: if the ends of the horseshoe face upward, good fortune will arrive from the heavens, if they face downward, it will flow up from the earth. The special circulation coins have been struck to represent both beliefs, so that they bring good fortune to everyone.
