Examples of the Nine Unknown Men making contact with the outer world are rare. There was, however, the extraordinary case of one of the most mysterious figures in Western history: the Pope Sylvester II, known also by the name of Gerbert d’Aurillac. Born in the Auvergne in 920 (d. 1003) Gerbert was a Benedictine monk, professor at the University of Rheims, Archbishop of Ravenna and Pope by the grace of Ortho III. He is supposed to have spent some time in Spain, after which a mysterious voyage brought him to India where he is reputed to have aquired various kinds of skills which stupified his entourage. For example, he possessed in his palace a bronze head which answered YES or NO to questions put to it on politics or the general position of Christianity. According to Sylvester II this was a perfectly simple operation corresponding to a two-figure calculation, and was performed by an automaton similar to our modern binary machines. This “magic” head was destroyed when Sylvester died, and all the information it imparted carefully concealed. No doubt an authorized research worker would come across some interesting things in the Vatican Library.
