St. Justinian was a sixth-century hermit who lived on Ramsey Island off Pembrokeshire. According to his Life, some sailors once told him that St. David was ill, and they took Justinian to see him – but during the journey Justinian realized that they were actually demons in disguise. So he recited Psalm 79, whereupon the sailors turned into crows and flew away.
