For similar drawings in the VMS, please look at the
images on folio 85r2 and 86v4. One set of four,
probably male, figures around the sun. One set of
four, probably female, figures around the moon. Lots
of objects being held - eggs, cups, bowls, wheat or
straw, flower, chain, cane, etc. (all up for debate).
One female figure points away from the viewer. Raw
images and some clean up I have done are at:

While these don't have the rings of letters around
them like f57v, they are surrounded by copy and have
possibly richer content in their illustration. In any
case, they are the most similar diagrams to the
figures on f57v.
