Omega

Omega: last letter of the Greek alphabet. This chapter begins at the end of the alphabet and therefore the circular structure of FW is invoked (O is also a circle).

Jesus said he was the "Alpha and Omega, the beginning and the end, the first and the last." (Revelation 22:13, KJV).

The beginning of this chapter is also in the shape of a delta: ∆ (a triangle). Delta is the fourth letter of the Greek alphabet. It is also the name given to the triangular shaped mouth of a river ie. the Nile Delta.

Prayers often begin with 'Oh...'

'Eau' is also French for 'water'.
