The long inscription quotes the Revelation (10,1):
'Then I saw another mighty angel coming down from heaven. He was robed in a cloud, with a rainbow above his head; his face was like the sun, and his legs were like fiery pillars.
The angel is standing with one leg on land and the other on the sea. He is holding a little book, which lies open in his hand; in its pages, the words of the angel to John are written:
Take the book and eat it. It will turn your stomach sour, but in your mouth, it will be as sweet as honey.
