Jn 1:7b ... that he-might-testify about the light, ...

The 2nd phrase has these 5 narrator words ... hina marturēsē peri tou fōtos (that he-might-testify about 'the light,' ...).

The 5 narrator words are top down, left to right. The 2 words hina marturēsē (that he might testify) are top down from the word "this-one," and tangent to John and the sides of "the light." The last 3 words "peri tou fōtos" (about the light) are left to right and top down to the sign of "the light" under "this-one."
