The rete is of the gothic (quatrefoil) type. Many of
the star names are clearly misplaced, e.g., Vega is labelled
Althair. In general, the star names have been associated with
the corresponding names of the modern stars. In some cases,
however, it seemed better to use the star's position to
determine the modern star, e.g., Althair is clearly Vega. In
other cases, the star intended is so ambiguous that no modern
star has been associated with a pointer.The Tropic of
Capricorn band ends in the head and tail of a dragon. This
rete is unusual in that the head of the dragon is on the
left-hand end. On the other retes in the collection that have
a zoomorphic Tropic of Capricorn, the head of the dragon is
at the other end, indicating the star Antares (on this rete
that star is labelled 'Cor Scorpionis').The zodiac on the
rete is labelled: ARIES , TAVRVS , GEMINI , CANCER , LEO ,
VIRGO , LIBRA , SCORPIO , SAGITTARIVS , CAPRICORN

, AQVARIVS , PISCES
