Cancer, the Crab,
from Bayer's Uranometria of 1603.
At the center is the four-star "Manger," and at the center of that, the
Praesepe or Beehive star cluster. Gemini, with bright Castor and
Pollux, is at the right, while the Sickle of Leo, with first magnitude
Regulus, is at left. Procyon, in Canis Minor, labelled "G," is down
toward bottom right, while the head of Hydra, the Water
Serpent, is down and slightly to the left. The dark
band marks the region around the ecliptic
in which the planets and Moon can be found.
