Ichthys (symbol)

The ichthys or ichthus (/ˈɪkθəs/), from the Greek ikhthū́s (ἰχθύς, 1st cent. AD Koine Greek pronunciation: [ikʰˈtʰys], "fish") is a symbol consisting of two intersecting arcs, the ends of the right side extending beyond the meeting point so as to resemble a fish.

In the Gospels

Fish are mentioned and given symbolic meaning several times in the Gospels. Several of Jesus' 12 Apostles were fishermen. He commissions them with the words "I will make you fishers of men". (Mark 1: 16-18). Having been resurrected, Jesus was given grilled fish in Luke 24:41-43.
