BISOSSII, SIBILLINA, Blessed. – Dominican mystic, born in Pavia c. 1287, died there on 19 March 1367. At the age of twelve she lost her sight and, instructed by Dominican Tertiaries, embraced the religious life. Having asked for but not obtained the miracle of healing, in conformity with patient Christ, at fifteen she shut herself in a cell built near the church of the Friars Preachers, where she remained in penance and visions for the rest of her life. Her cult was confirmed on 17 August 1854 by Pius IX; her feast is celebrated on 23 March. Her body is venerated in the cathedral of Pavia.
