Sigismund of Burgundy
king of the Burgundians
Feast: 1 May (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
At Saint-Maurice-en-Valais in Raetia, in present-day Switzerland, the deposition of Saint Sigismund, who, king of the Burgundians, converted from the Arian heresy to the Catholic faith, established in this place a choir of monks who sang hymns unceasingly before the tomb of the martyrs, atoned for the crime he had committed by penance, tears and fasting, and met his death in the territory of Orléans, drowned in a well by his enemies.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
The Roman Martyrology remembers him on 1 May as a king of the Burgundians who left Arianism for the Catholic faith, did penance for his crime and was drowned by his enemies.
