It is dawn on Easter Sunday. According to Christian theology, the death and resurrection of Christ is what makes Heaven attainable to sinners, so it’s appropriate that this Cantica—whose characters are all ultimately bound for Heaven—opens on Easter morning. Calliope is the Muse of epic poetry, hence Dante’s invocation of her at the beginning of this Cantica. According to Dante’s geography, the Earthly Paradise, or Garden of Eden, is located at the summit of Purgatory. In Dante’s mind, after Adam and Eve were expelled from Eden, nobody else lived in this Hemisphere. The stars symbolize the so-called cardinal virtues of
justice, prudence, temperance, and fortitude—virtues that pagans, uninformed by Christian grace, could practice.
