Palazzo Schifanoia, north wall, month of September.In the centre “the sign of Libra”. The decans around Libra do not offer interpretative certainties. The identity of the first, a curious flute player, and of the second, with animalistic characteristics, perhaps a representation of Engonasin, father of Calisto, i.e. the Big Dipper, is very doubtful. The third decan, composed of two characters, is well described by Albumasar and alludes to the constellation of Centaurus.Frescoes attributed from time to time to Cosmè Tura or to Ercole de' Roberti or to Gherardo di Andrea Fiorini.
