(Saints) (July 10) (6th century) Sigisbert, an Irish Saint, a follower of Saint Columbanus, settling in the Swiss Canton of the Grisons, with the help of Placidus, lord of the district, founded, at the end of the sixth century, the famous Abbey of Dissentis. Saint Placidus was put to death by evil-doers, described as enemies of religion, about A.D. 600, and was buried in the same grave with Saint Sigisbert, who did not long survive him.
