Names For This Star

Procyon is the Greek name for Alpha Canis Minoris from the earliest times. In English the meaning of the Greek roots would be something like "Before (or in Front of?) the Dog." The star was sometimes referred to in Latin as Antecanis, which, according to Allen is equivalent to "Procyon".

Other names for the star are Elgomaisa or Algomeysa which are derived from the Arabic name Al Shi'ra Shamiyyah, meaning "The Northern Sirius."
