Christina Rossetti wrote 'As froth on the face of the deep' in 1893 - Rossetti lived during a time of scientific upheaval (e.g. Darwin’s On the Origin of Species, 1859), which led to a crisis of faith for many - However, she moved in the opposite direction - turning more deeply toward Christian devotion - This poem illustrates the idea that hope, unless rooted in God, is empty and fleeting, much like “froth” or “foam”
