The acorn has also been considered to be magical for centuries. The Roman Goddess Diana is very often shown wearing a string of acorns around her neck. The Norse God Thor is said to have taken shelter under an oak tree from a thunderstorm. This led to the belief that if one places an acorn on their windowsill, the house will be protected from lightening strikes.
There is an old legend in Great Britain that the acorn can deter aging. All one has to do is carry an acorn somewhere on their person. This is thought to keep that person young forever. This probably has something to do with the fact that oak trees have a very long life.
