It introduces theoretical perspectives from the social sciences and subjects them to empirical scrutiny using data from Greek and Demotic papyri as well as comparative evidence. Although building on recent scholarship, it offers some provocative arguments that challenge prevailing views. For example, patterns of land ownership are linked to population density and are seen as one aspect of continuity between the Ptolemaic and Roman period. Fiscal reform, by contrast, emerge

Ingrid Monson juxtaposes musicians’ talk and musical examples to ask how musicians go about "saying something" through music in a way that articulates identity, politics, and race. Through interviews with Jaki Byard, Richard Davis, Sir Roland Hanna, Billy Higgins, Cecil McBee, and others, she develops a perspective on jazz improvisation

With essays by leading academics, critics and practitioners, the book traces the British prose poem’s unsettled history and reception in the UK as well as its recent popularity. The essays cover the nineteenth, twentieth and twenty-first centuries exploring why this form is particularly suited to the modern age and yet can still be problematic for publishers, booksellers and scholars. Refreshing perspectives are given on the Romantics, Modernists and Post-Modernists, among them Woolf, Beckett and Eliot as well as more recent poets like Seamus Heaney, Geoffrey Hill, Claudia Rankine, Jeremy Over and Vahni Ca

Thanks to clandestine instruction from a local maestro di cappella and despite the church hierarchy?s vehement opposition to all convent music Vizzana became the star of the convent, composing works so thoroughly modern and expressive that a recent critic described them as \u201chistorical treasures.\u201d But at the very moment when Vizzana?s works appeared in 1623 she would be the onl
