Chaucer, Astrolabe Chart 4, Rete
Since the pointer Stars on the rete of an astrolabe
are neccessarily the Brightest Stars in the sky,
& preference is given to the circumpolar area,
most are outside the Zodiacal constellation they align with.
Notice in particular the 8 Stars lying within the band of Zodiacal signs
in gold & in particular that 4 of them rotate closely
around Polaris & the Pole of the Ecliptic,
while 4 are closer to & one of them just hugs the Zodiacal band.
The 8 in gold I have tentatively identified on the chart on p.4 below.
If we compare this with the inner circle of f57v,
we find very much the same arrangement
if we take the outstretched fingers of the figures as our pointers.
