Jupiter

[Diane]

Geomantic figures are an old tradition in north Africa, and probably pre-Islamic.

Correlation to various asterisms is attested by a device I've often mentioned, treated by Emlie Savage-Smith some years ago in a small book entitled, A thirteenth-century divinatory device'.. but see also her later paper "Another look at....'

Michel Scot's works on astronomy, composed in Sicily, include geomantic forms in imagery not actually showing the GrecoRoman figures, but which are named by translating their characters to the nearest Roman equivalent as e.g. Venus or Juppiter(sic.).

I haven't looked at that material for a while but as I recall, Scot's "Juppiter" is  associated with the geomantic figure for the Pleiades (using the same system employed in that geomantic device described by Savage-Smith). 

Cornelius Agrippa's system comes late, and while it seems to be based on a genuine source - he understands the African system for generating the figures - his given relationship between asterisms and geomantic figures appears not to have been original in Africa, and as an artificial system appears to have been a highly variable set of correspondences..

My guess is that the image from GKS 79 °2 (shown above) was derived at some remove from Scot. 

Scot's "Juppiter" is illustrated in Jim Tester's History of Western Astrology (Boydell Press) if anyone wants to see it.
