The Sisters of Loretto prayed a nine-day novena to St. Joseph, patron saint of carpenters. On the final day, an elderly man arrived with a donkey, worked alone in total secrecy, used no nails, no screws, no glue, and vanished without payment.

A U.S. Navy lab identified the wood as Picea spruce, yet it does not match any known species cataloged by science. No local lumber was ever purchased. Even physicists say the double-spiral design is key to its impossible strength.
