A scrupulous edition and translation of the surviving correspondence of Gregory Akindynos, one of St. Gregory Palamas's most dangerous adversaries...a major scholarly contribution to our knowledge of fourteenth-century Byzantine Hesychasm. It is indeed a pleasure to acknowledge and salute Professor Hero's achievement. Scholars will remain in her debt for a long time to come...an indispensable and invaluable addition to the growing literature on Byzantine Hesychasm.
