The find of Eva Seidenfaden of Scheiner’s original diagram of the 1630 Rome halo (Applied Optics 50 F60-F63 (2011)), which has thought to be lost forever, is discussed. The diagram show a legendary halo about which she has published before with Tape and Können (Applied Optics H72-H84 (2008)), and which has helped Huygens to develop his halo theory. NB: the Nature article has been republished on 30 Sep 2011 in Scientific American.
