Visions were common in mediaeval literature, ordinary folk would see Mary or one of the Saints in the clouds, up a tree, in the porridge, or just suspended in the air. The Vision of MacConglinne (Aislinge Meic Conglinne) is regarded by many as the finest satire in the Irish language. Written in the late 11th century it recounts the valiant efforts of Aniér MacConglinne to purge the King of Ireland, Cathal mac Finnguine of his gluttony – which is portrayed as a devil living in the King’s throat.
Disappointed by the hospitality of the people of the city of Cork, who are less than impressed by his singing, he composes a satire on them which results in his being imprisoned and condemned to crucifixion. On the eve of his execution, Meic Conglinne is visited by an angel of God and granted a vision, not of divine inspiration, but of a land made entirely of food. A concept close to the heart of Modern Salt.
