It’s been years since I looked into this, but Alfonso’s Astromagia BAV Reg Lat 1283 and Petrus de Abano’s Astroloabium Planum are certainly related, though I believe the relationship is an indirect one (one doesn't derive from the other, but they derive from the same Eastern sources, including Albumasar).
For instance, these are the first two degrees of Scorpio.
Astromagia:
1 Figura de ombre con una lanza.
2 Figura de ombre sobrel marfil.
Astrolabium Planum (note that the two illustrations were accidentally swapped):
1 Vir cuspidem tenens in manu sua.
2 Vir sedens in elephante.
Another related tradition which might include illustrations of the individual signs is You are not allowed to view links. Register or Login to view.. Several versions of the man with a spear and the elephant rider appear among the first images for Scorpio. In this text, the origin of the images as fragments of constellations is clearer. The images are not clearly numbered and separated from each other, so I am not sure that each sign includes the 30 degrees (plus, likely, the 3 decans).
