This book presents St Macrina the Younger (c. 327-379), eldest sister of Ss Basil the Great and Gregory of Nyssa. All the sources of Macrina's life are gathered together, translated afresh into English, and provided with up-to-date introductions and notes. Documents include: Testimonies of St Basil, St Gregory Nazianzen's epigrams on Macrina and her siblings; Gregory of Nyssa's letter 19 which appears in English for the first time; The Life of Macrina, a jewel of fourth-century Christian biography; and the dialogue On the Soul and Resurrection in which Macrina appears as the Teacher expounding Christian doctrine with reasoned argument. The introductory shows how Macrina gradually changed the family household of Annisa into the proto-monastic community that became model of the monasticism that has come down under Basil's name. A specially commissioned icon, a map of Central Anatolia, and a report of the author's expeditions to ancient Pontus are included.
