The word ‘between’ can refer to a connection, such as tying a rope between two trees, or a separation, such as a barrier coming between two people.
How do you interpret the use of ‘between’ in stanza 4?
We watched it apart, and perhaps that was my mistake,
letting the half-darkness fall over you in the city,
while I traced its spreading hand across the fields,
following the rooks, flying in threes to roost.
But as the sun became quarter, then half moon,
it unlocked in me, and I saw us connected again,
by the day’s slowing to monochrome, by the mid-day midnight breeze
and by the moon’s shadow passing over and between us.
