In the Old Testament Book of Daniel, duringt a banquet hosted by King Belshazzar, mysterious writing ("Mene, Mene, Tekel, Upharsin") appeared on the wall, written by a disembodied hand. The visionary Daniel was summoned and interpreted this message as signalling the imminent end of the Babylonian kingdom. That night, his prophesy was fulfilled as Belshazzar was killed and the Persians sacked the capital city.
