Joachim of Fiore has been described as the most singular and fascinating figure of mediaeval Christendom. This title explores his unique understanding of history and looks at the powerful influence of his ideas.

Joachim of Fiore proclaimed a philosophy of history which exercised a powerful influence in succeeding centuries. This book traces the influence of his prophecies concerning a Third Age of the Spirit to come, as later expressed in the themes of New Spiritual Men, Last World Emperor, Angelic Pope, and Renovatio Mundi. It shows that these ideas were not only the mainspring of various heterodox groups, but also engaged the attention of certain church leaders, university scholars, Renaissance thinkers, Protestant theologians, and political rulers down to the seventeenth century.

Joachim of Fiore (c.1135-1202) remains one of the most fascinating and enigmatic figures of medieval Christianity. In his own time, he was an influential advisor to the mighty and powerful, widely respected for his prophetic exegesis and decoding of the apocalypse. In modern times, many thinkers, from Thomas Müntzer to Friedrich Engels, have hailed him as a prophet of progress and revolution. Even present-day theologians, philosophers and novelists were inspired by Joachim’s vision of a Third Age of the Holy Spirit. However, at no time was Joachim an uncontroversial figure. Soon after his death, the church authorities became suspicious about the explosive potential of his theology, while more recently historians held him accountable for the fateful progressivism of Western Civilization.

This renowned study provides a `map' of the influence of the powerful, original theology of Joachim of Fiore (c.1132-1202). Radically revised since its first publication in 1987, and augmented with further prophetic voices and symbols from the past, it confirms the deep structures of visions of the future while demonstrating and questioning the persistence of Joachimist themes in the twentieth-century fin de siecle.

The Reformation of Prophecy illuminates the significant shifts in the Protestant reformers' engagement with the prophet and biblical prophecy-shifts from advancing the priesthood of all believers to strengthening Protestant clerical identity and authority to operating as a site of polemical-confessional exchange concerning right interpretations of Scripture.

The essays here collect the author's further researches since the publication of her pathbreaking Influence of Prophecy in the Later Middle Ages in 1969. In part stimulated by responses to the book, they also show the extent to which the field then opened up has now expanded. In the last forty years a cultural shift in the meaning of 'history' has brought to the forefront an interest in how people have charted their future by the signs given in their historical heritage. Both pessimistic and optimistic readings of history meet in medieval Western Europe and colour the thought, art, even the politics of the Renaissance. In particular, the powerful vision of Joachim of Fiore activated a reading of history which culminates in a flowering of a 'third age'. These essays attempt to portray some of the strange and moving shapes which thronged the imagination as men and women looked to their prophetic future.
