Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This essay collection studies the Apocalypse and the end of the world, as these themes occupied the minds of biblical scholars, theologians, and ordinary people in Antiquity, the Middle Ages, and Early Modernity. It opens with an innovative series of studies on "Gendering the Apocalypse," devoted to the texts and contexts of the apocalyptic through the lens of gender. A second section of essays studies the more traditional problem of "Apocalyptic Theory and Exegesis," with a focus on authors such as Augustine of Hippo and Joachim of Fiore. A final series of essays extends the thematic scope to "The Eschaton in Political, Liturgical, and Literary Contexts." In these essays, scholars of history, theology, and literature create a dialogue that considers how fear of the end of the world, among the most pervasive emotions in human experience, underlies a great part of Western cultural production.

Callimachus of Cyrene, born ca. 310 BCE, after studying philosophy at Athens, became a teacher of grammar and poetry at Alexandria. Ptolemy II Philadelphus of Egypt (reigned 285-247) made him when still young a librarian in the new library at Alexandria; he prepared a great catalogue of its books.

Callimachus was author of much poetry and many works in prose, but not much survives. His hymns and epigrams are given with works by Aratus and Lycophron in another volume ("no. 129") of the Loeb Classical Library. In the present volume are included fragments of the "Aetia" (Causes), aetiological legends concerning Greek history and customs; fragments of a book of "Iambi"; 147 fragments of the epic poem "Hecale," which described Theseus's victory over the bull which infested Marathon; and other fragments.

We have no explicit information about the poet Musaeus, author of the short epic poem on "Hero and Leander," except that he is given in some manuscripts the title Grammatikos, a teacher learned in the rhetoric, poetry and philosophy of his time. He was obviously a follower of the Egyptian poet Nonnus of Panopolis, of the fifth century AD, and his poem seems also to presuppose the "Paraphrase of the Psalms" of Pseudo-Apollinarius which can be dated to the period 460-470.

Musaeus takes up a subject whose first detailed treatment is preserved in Ovid's "Heroides" (Epistles 18 and 19), but he presents it in a quite different manner. Among the literary antecedents to which this learned grammatikos expressly alludes, the most prominent are Books 5 and 6 of the "Odyssey" and Plato's "Phaedrus." He draws too on the "Hymns" of Proclus and the "Metaphrasis of the Gospel of St. John" byNonnus. He was most probably a Christian Neoplatonist writing a Christian allegory.

Around 1700 the notion of gallantry emanated from France as a stylistic and ethical model for Europe, with the novel acting as the principal school for gallant living. This comparative study is a contribution to a cultural history of gallantry. It gives a detailed account of the reception of a ~gallant discoursea (TM) in German narrative prose, tracing it from its French sources (ScudA(c)ry) through authors such as Bohse and Hunold to its elaboration by Christoph Martin Wieland. Thus a picture is formed of a oeRomanesque narrationa in the 18th century.
