The Ichthys (or Ichthus), derived from the Greek word ikhthū́s (ἰχθύς), is a Christian symbol consisting of two intersecting arcs that form the shape of a fish. The right side extends beyond the meeting point, resembling a fish profile.
In early Christianity, the Ichthys served as a secret sign among believers, particularly during times of persecution. More than just a visual representation, the Greek letters ΙΧΘΥΣ (or ΙΧΘΥϹ with a lunate sigma) form an acronym for:
I (Iota – Ἰησοῦς, Iēsoûs) – Jesus
Ch (Chi – Χρῑστός, Khrīstós) – Christ (Anointed One)
Th (Theta – Θεοῦ, Theoû) – of God
Y (Ypsilon – Υἱός, (H)uiós) – Son
S (Sigma – Σωτήρ, Sōtḗr) – Saviour
Together, this phrase translates as "Jesus Christ, God's Son, Saviour.
