Pisces is one of the Zodiac symbols. Each symbol, though apparently is connected to some animal as the Zodiac means, there are hidden religious meanings. During the Age of Pisces, the Fish was the symbol of divinity and the Sun God fed the multitude with two small fishes. The frontispiece of Inman’s Ancient Faiths shows the goddess Isis with a fish on her head; and the Indian Savior God, Krishna, in one of his incarnations was cast from the mouth of a fish.
Not only is Jesus often referred to as the Fisher of Men, but as John P. Lundy writes: “The word Fish is an abbreviation of this whole title, Jesus Christ, Son of God, Savior, and Cross; or as St. Augustine expresses it, ‘If you join together the initial letters of the five Greek words, Ἰησοῦς Χριστος Θεου Υιὸσ Σωτήρ, which mean Jesus Christ, Son of God, Savior, they will make ΙΧΘΥΣ, Fish, in which word Christ is mystically understood, because He was able to live in the abyss of this mortality as in the depth of waters, that is, without sin.'” (Monumental Christianity.) Many Christians observe Friday, which is sacred to the Virgin (Venus), upon which day they shall eat fish and not meat. The sign of the fish was one of the earliest symbols of Christianity; and when drawn upon the sand, it informed one Christian that another of the same faith was near.
