The Mary Ann Simpson (1857-1915) memorial stained glass window is in St David’s Anglican Cathedral, Hobart. The lancet window features St Michael as a knight wearing armour of the late medieval period and wearing a sword. He is killing a red dragon which lies at his feet with a spear. St Michael and the dragon are coming out of a representation of what appears to be a niche of delicate stonework in Gothic style with pointed arches.
