Ichthys Symbol - Meaning and History of the Christian Fish Sign #288286 (License: Personal Use)

This minimalist black-line ichthys symbol-formed by two intersecting arcs resembling a fish-is one of Christianity’s oldest visual identifiers. Originally used by early Christians as a secret sign during persecution, it encodes the Greek word “ΙΧΘΥΣ” (Ichthys), an acronym for “Jesus Christ, God’s Son, Savior.” Its clean, universal design makes it instantly recognizable across cultures and contexts.
