📑 Fish | Wikipedia

Annotated Fish (Wikipedia)

Early Christians used the ichthys, a symbol of a fish, to represent Jesus, because the Greek word for fish, ΙΧΘΥΣ Ichthys, could be used as an acronym for "Ίησοῦς Χριστός, Θεοῦ Υἱός, Σωτήρ" (Iesous Christos, Theou Huios, Soter), meaning "Jesus Christ, Son of God, Saviour". ❧

A fact that I suspect that few Christians know. I wonder if the “Darwin fish” has a similar acronymization?
