This volume is an essential supplement to Pastoral poetry of the English Renaissance: An anthology (2016). The full-length Introduction examines English Renaissance pastoral against the history of the mode from antiquity to the present, with its multifarious themes and social affinities. The study covers many genres - eclogue, lyric, georgic, country-house poem, ballad, romantic epic, prose romance - and major practitioners - Theocritus, Virgil, Sidney, Spenser, Drayton and Milton. It also charts the circulation of pastoral texts, with implications for all early modern poetry. All poems in the Anthology were edited from the original texts; the Companion documents the sources and variant readings in unprecedented detail for a cross-section of early modern poetry. Includes notes on the poets and analytical indices. The Companion is indispensable not only to users of the Anthology but to all students and advanced scholars of Renaissance poetry.
