After playing around with zoom & gamma correction (taking the scans
from the Beinecke site as a basis), I am pretty much convinced that the
loops are *not* filled in (the area in the center of the loops is still lighter
than the surrounding line) :(
Nevertheless, I think the main purpose of the "elaborated" Cancer symbol is to avoid making the resemblances too obvious - the same goes for the Jupiter symbol.
