Palazzo Schifanoia, north wall, month of August: in the centre, “the sign of Virgo”. Around the zodiac sign of Virgo we still find characters taken from the Indian and Persian sphere of Albumasar: on the left Proserpina, in the centre a figure difficult to interpret astrologically and on the right a woman in the act of praying who, according to recent studies, seems to refer to Isis.Detail.Frescoes attributed from time to time to Cosmè Tura or to Ercole de' Roberti or to Gherardo di Andrea Fiorini.
