Read an interesting interpretation of the number 666 (from Revelation) by an early church father, Irenaeus and Hippolytus;

Irenaeus connected the number 666 with the Greek word "teitan," which means "giant," and is related to the Titans, a race of giants in Greek mythology.

In Greek gematria, a system where letters are assigned numerical values, the word "teitan" adds up to 666. Irenaeus favored this interpretation because it was not tied to a specific ruler or figure, but to an evil tyrant, and because it was associated with the demonic realm.

Note the use of the word "tartaros" in 2 Peter 2:4 refers to a lower realm in Greek mythology where the Titans were imprisoned. This adds another layer to the interpretation, linking the number 666 to the demonic realm.
