A friend. Ok, it was Eulalia again, but I do have more than one friend, I promise. Eulalia was asking about 11th and 12th century food sources. I was more than a little surprised that she had not heard of the vision of Mac Conglinne.
In a nutshell, and if you tell this story, Conchobhar, you’ll want to do a better job of memorizing the lists of foods, but in a nutshell, it’s a parody of other “religious vision” stories.
Aniér MacConglinne is a scholar from Armagh. And he hears that the King, Cathal mac Finnguine, is suffering from a demon of gluttony. So he goes to the court and grinds his teeth together so loudly that court is disrupted and, in his first bit of generosity in 3 years, the king gives MacConglinne an apple. He talks the king out of more and more apples, and eventually convinces the king to fast with him. Then he binds the king to the wall, and eats meats in front of him. Eventually and with much complaint, the demon is pulled out. Anier burns him up and banishes him.
*obviously* I should learn this, if only for the litany of foods listed in the Vision. I think the Early Irish Poetry book has a better copy than wikipedia.
