What is "guglielma"

Guglielma (died 1279-82) was an Italian woman of the 13th century, who practiced and preached an alternative, feminized version of Christianity in which she predicted the end of time and her own resurrection as the Holy Spirit incarnate. She is now the unofficial patron saint of Brunate. A painting from ca. 1450 depicting Guglielma blessing Abbess Maddalena Albrizzi and an unknown donor hangs in the Church of San Andrea in Brunate. Barbara Newman has attempted to identify the kneeling figures in the painting as Guglielma's followers, Sister Maifreda da Pirovano and Andrea Saramita, but this is contested.
