Gulstà de Rhuys
British monk
Feast: 27 November (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
At Beauvoir-sur-Mer on the French coast in the territory of Nantes in Brittany, Saint Gulstan, monk, who, having escaped as a young man from the hands of pirates and been taken in by Saint Felix, then a hermit, shone in the monastery of Rhuys where, though illiterate, he recited the psalter by heart and cared for seafarers.
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 27 November as an illiterate monk of Rhuys who knew the psalter by heart and cared for seafarers.
