Winter Asterisms 

By Andrei Dorian Gheorghe

While discussing stars and constellations 

with Claudius Ptolemy (100-170), 

I told him that, in addition to the asterisms 

Winter Triangle 

(Procyon, Sirius, Betelgeuse) 

and Winter Hexagon 

(Pollux, Capella, Aldebaran, 

Rigel, Sirius, Procyon), 

there should also be 

the Winter Quadrilateral 

(Procyon, Sirius, Betelgeuse, Rigel). 

.

But Ptolemy got annoyed: 

-There are already too many asterisms 

in the same area of the sky 

and you are downright tiring...
