The water fountain of the monument was designed as a sculpture that actively pumps water into a dish, when a metal knob was pushed. The scene is of Moses striking the rock at Horeb (Exodus. XVII. IV-VI). To the left, a Jewish woman holds a cup to the lips of her child.
St Lawrence, the deacon and martyr, is shown with a gridiron, the instrument of his death. St. Mary Magdalene is shown with her emblem, the ointment jar with which she cleansed Christ’s wounds.
