The age of Pisces began AD 1 and will end AD 2150. With the story of the birth of Christ coinciding with this date, many Christian symbols for Christ use the astrological symbol for Pisces, the fishes. The figure Christ himself bears many of the temperaments and personality traits of a Pisces, and is thus considered an archetype of the Piscean. Moreover, the twelve apostles were called the "fishers of men," early Christians called themselves "little fishes," and a code word for Jesus was the Greek word for fish, "Ikhthus." With this, the start of the age, or the "Great Month of Pisces," is regarded as the beginning of the Christian religion. Saint Peter is recognized as the apostle of the Piscean sign.
