Even so Giotto adds an element that lifts the story even more into narrative. Joachim looks back resentfully while turning his body as though to protect the lamb that he holds tenderly as he would the baby they don’t yet have; this is the lamb of God, sacrificed for the sins of the world. Nothing in the legend hints at such an interpretation but Giotto’s creativity saw deeply into the story and turned it into part of the narrative of redemption.
