The rete is of the other (ornate) type. The strapwork
on this rete resembles that found on astrolabes from the
Louvain workshops. The scripts show quite a lot of
variablity. Extensive use is made of shading to suggest a 3-D
effect, both on the lattice and on the star pointers; the
over-all effect is of interwoven lattice (trompe l’oeil) .The
zodiac on the rete is labelled: Aries ♈ , Taurus ♉ , Gemini ♊
, Cancer ♋ , Leo ♌ , Virgo ♍ , Libra ♎ , Scorpius ♏ ,
Sagitarius ♐ , Capricornus ♑ , Aquarius ♒ , Pisces ♓

nut.
