In Ancient Macedonia, people carried amulets made out of bat bones. Bats were considered the luckiest of all animals, thus their bones were sure to bring good luck. In China, bats are also considered good luck or bringers of happiness, as the Chinese word Fu is a homophone for both "bat" and "happiness".[2] Flying fox wings were depicted on the war shields of the Asmat people of Indonesia; they believed that the wings offered protection to their warriors.[16] The 10th century Geoponica stated that affixing a bat's head to a dovecote would prevent domestic pigeons from straying, and Pliny the Elder's Natural History asserted that carrying a bat three times around a room and then nailing it head-down to a window would magically protect sheep pens.[4]
