St. Elizabeth of Hungary, the patron saint of bakers, lacemakers, and the homeless, was the daughter of the King of Hungary and renowned for her care of the poor. She was caught sneaking some loaves of bread to the poor, which miraculously turned to roses when they were revealed.
I have a soft spot for "bread alone" narratives, and the imagery of good, practical bread turning into good, beautiful (but not practical) roses warms my artist heart. Maybe that's the explanation for her connection to lacemakers?
But the roses+bread+princess+religious imagery thing came to mind during this season's finale of Game of Thrones, making me think of a certain princess associated with roses, saints, and the poor...
