I seem to have gotten into the habit of collecting Magdalens. St Mary Magdalene is always featured in Crucifixion scenes, weeping bitterly at the feet of Christ - as she is here in the east window in Seighford Church.
She always throws a long, bright splash of scarlet into the depiction, as she (traditionally) always had long red hair (as well as a scandalous previous life).
July 22nd is her feast-day.
