Alpha and Omega

Not a mythic origin tale in the sense of a created entity; the phrase originates in the Greek-language Christian scriptural tradition. In the Book of Revelation (Koiné Greek) the divine speaker declares 'I am the Alpha and the Omega' (ἐγώ εἰμί τὸ Ἄλφα καὶ τὸ Ὦ), using the names of the first and last letters of the Greek alphabet as a concise appellation communicating that God or Christ is both origin and terminus of all things. The symbolic technique has analogues in other Abrahamic texts (e.g., Hebrew usages such as emet and Qur'anic names al‑Awwal/al‑Ākhir) but the specific Alpha/Omega formulation arises from the Greek New Testament milieu.

As a symbol the 'appearance' is graphic: the letters Alpha (Α/α) and Omega (Ω/ω) in juxtaposition. In Christian iconography they are often placed to the left and right of Christ's head, sometimes within his halo, and appear suspended from the arms of the cross in early Christian art (e.g., Roman catacombs, cruces gemmatae). The term is not represented as a bodily or anthropomorphic form in the supplied sources.

No personal or agentive abilities are ascribed in the cited materials; rather, the formula functions performatively as a divine self-identification asserting God's or Christ's eternity and comprehensive sovereignty over time and existence ('the beginning and the end'). It operates theologically and iconographically to communicate totality, not as an actor that interacts independently with humans.
