Star Tales - Canis Minor (ianridpath.com)
Representing the smaller of the two dogs of Orion, Canis Minor originally consisted of just the bright star Procyon, known in Greek as Προκύων (Prokyon), meaning ‘before the dog’ or ‘foredog’. This name, used by the Greeks for both the star and the constellation, comes from the fact that it rises earlier than its more prominent kennel-mate Canis Major which Ptolemy called simply Κύων (Kyon), the Dog.
