The fish symbol, representing both Jesus and his followers, is an ancient one in Christianity. The master Christian told his disciples: "I will make you fishers of men" (Matthew 4:19). But the fish, through an acrostic, also became a symbol of the founder of Christianity himself. The ICHTHUS symbol helped Christians identify one another as believers.
One of the oldest symbols of the cross is the anchor. Originally a symbol of hope, the anchor takes on a much more spiritual meaning: the hope of resurrection since Jesus came off the cross and out of the tomb.
The symbol probably comes from these verses in Hebrews 6:19, 20: "Which hope we have as an anchor of the soul, both sure and stedfast, and which entereth into that within the veil; Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchisedec."
The anchor is found in the first-century cemetery of St. Domitilla, the second and third century epitaphs of the catacombs, and especially in the oldest parts of the cemeteries of Sts. Priscilla, Domitilla, Calixtus, and the Coemeterium majus.
