This is Page 47 of the bound volume of The Deer's Cry at the Manx Museum.

A multitude of colours and patterns may be representing the rewards? Is my imagination running away with me and playing tricks with me? The main things I see on the page are a rabbit (or hare) and a left hand white glove. I looked up both these things on the internet and was very surprised by what I found.

In Celtic mythology and folklore the hare is very important and In Irish folklore the hare is also often associated with the Otherworld (Aos Si) community whose world was reached through mists, hills, lakes, ponds, wetland areas, caves, ancient burial sites, cairns and mounds. Shapeshifters were often said to take the form of the hare. There is a legend that the Celtic warrior Oisin hunted a hare, wounding it in the leg. Oisin followed the wounded animal into a thicket where he found a door leading down into the ground. He went in and came to a large hall where he found a beautiful young woman sitting on a throne bleeding from a leg wound.. The Deer's Cry is St. Patrick's verse and at the time when legend sates that he was turned into the shape of a deer when the Irish king's men were trying to find him and kill him. Was Knox thinking of this in his illustration or am I being far too fanciful?
