Awhile ago, we were driving around with our friend Beverly, who was visiting. And she asked what is the meaning of all the stars on houses, barns, and yards. I think people not from this area are surprised when they see them, they are all over our area, and you can hardly go a block without seeing at least one. About 300 years ago, groups of religious refugees came to Pennsylvania, most speaking German. They collectively came to be known as "Pennsylvania Dutch". And they continued their tradition of painting large geometric patterns on their barns. A story slowly evolved that these were hex signs to keep evil spirits away, maybe because the word HEX means witch in German, but there is no proof of this. Experts actually disagree on the symbolism of the origional stars. Folk tradition suggests love, hope harmony, energy, and fire protection. Colors had significance, too. Blue for peace, green for growth, white for purity. Nowadays they are sold everywhere and just used for home decoration.
"He determines the number of the stars
and calls them each by name.
Great is our Lord and mighty in power;
his understanding has no limit."
