Once upon a time, a waggoner's cart, heavily laden with wine, became stuck fast. Despite all his efforts, he could not move it.
It chanced that Our Lady came by. Seeing the poor man's distress, she said to him, "I am tired and thirsty. Give me a glass of wine, and I will set your cart free."
"Willingly," answered the waggoner, "but I have no glass to give you the wine."
Then Our Lady plucked a little white flower with red stripes, called field bindweed, which looks very like a glass, and gave it to the waggoner. He filled it with wine, and Our Lady drank it. In that same instant, the cart was set free, and the waggoner could drive onwards.
The little flower is still always called Our Lady's Little Glass.
