The page comes in a treatise devoted to astronomy and astrology toward the end of a 15th C Netherlandish manuscript on natural history. (For the page, see image 00249). The treatise is bound with a description of a journey to the Holy Land. That's all I know, and I can't even come up with a writing exercise to go with it. Over to you.
