At the beginning of the first century, the Sun on the vernal equinox passed from Aries to Pisces (1 A.D. to 2150 A.D). That harmonizes with the mentioned lamb and fish in the gospels. The man carrying a pitcher of water (Luke 22:10) is Aquarius, the water bearer, who is always seen as a man pouring out a pitcher of water. He represents the Age of Aquarius, the age after Pisces, and when the Sun leaves the Age of Pisces (Jesus), it will go into the House of Aquarius.
