The strange dense black wriggling clouds are the mingling of smoke from burning ships, aircraft carriers with their lethal combination of aviation gasoline and fuel oil burning fiercely.
In the biblical sense these clouds recall the heavy water-laden clouds of the Deluge. (Genesis Ch 6-7)
A smudged dove - the Holy Spirit - struggles to emerge in the upper right window, while in the left is a rainbow with the clouds parting to reveal the sun - recalling Noah's story with God's renewed Covenant. (Genesis 9: 8-11)
These gloomy battle clouds, including a dispersing Hiroshima nuclear cloud, have a peace message: the dove is also a universal symbol of peace, while the dawn sky offers hope of a new beginning.
Christ's Cross in the upper centre panel is filled with smaller playful white doves: The Holy Spirit at work and play.
Whales and dolphins frolic in a procession across the window. In a joyful freeing way, they represent God's presence - as angels would have done in more traditional religious windows. They hint that they are the intelligent ones who do not go to war.
Below, to the left, is a school of innocent looking perch, with their flashing silver sides spelling PAX: Latin for peace. This is a fleeting message, for in the next instant the fish will have changed positions and that reflected word will have disappeared forever: a reminder that we too may have brief flashes of inspired truth to grasp and hold in our lives.
Peace is also written in 28 other languages around the border of the window. Whatever part of the world you are from, the word for peace may be recognised.
Every other word can be read from inside or outside, offering peace not only within the cathedral but to those passing by on the street.
