Something about pagan doodles on the pages of Hosea seems connected to our project in some odd way I haven't yet thought through, but I thought I'd post it here.
Holcot's Moralitates are a collection of material for the use of preachers in which the 'picture' [memory] technique is lavishly used....He places such images, in imagination, on the pages of a Scriptural text, to remind him of how he will comment on the text.

He even places on the text of the prophet an image of Cupid, complete with bow and arrows! The god of love and his attributes are, of course, moralised by the friar, and the 'moving' pagan image is used as a memory image for his moralising expansion of the text.
