"The Countess of Pembroke's Arcadia, also known simply as the Arcadia or the Old Arcadia, is a long prose work by Sir Philip Sidney written towards the end of the sixteenth century, and later published in several versions. It is Sidney's most ambitious literary work, by far, and as significant in its own way as his sonnets. The work is a romance that combines pastoral elements with a mood derived from the Hellenistic model of Heliodorus. In the work, that is, a highly idealized version of the shepherd's life adjoins (not always naturally) with stories of jousts, political treachery, kidnappings, battles, and rapes. As published, the narrative follows the Greek model: stories are nested within each other, and different storylines are intertwined."
