This study focuses on the praeceptor amoris, or teacher of love, as that persona appears in English poetry between 1500 and 1660. Some attention is given to the background, especially Ovid and his Art of Love. A study of the medieval praeceptor indicates that ideas of love took three main courses: a bawdy strain most evident in Goliardic verse and later in the libertine poetry of Donne and the Cavaliers; a short-lived strain of mutual affection important in England principally with Spenser; and the love known as courtly love, which is traced to England through Dante and Petrarch and which is the subject of most English love poetry. In England, the praeceptor is examined according to three functions he performs: defining love, propounding a philosophy about it, and giving advice. Through examining the praeceptor, poets are seen to define love according to the division between body and soul, with the tendency to return to older definitions in force since the troubadours. The poets as a group never agree what love is. Philosophies given by the praeceptor follow the same division and are physically or spiritually oriented. The rise and fall of Platonism in English poetry is examined through the praeceptor amoris who teaches it, as is the rise of libertinism. Shakespeare and Donne are seen to have attempted a reconciliation of the physical and spiritual. Advice, the major function of the praeceptor, is widely variegated. It includes moral suasion, advice on how to court, how to start an affair, how to maintain one, how to end one, and how to cure oneself of love. Advice also includes warnings. The study concludes that English poets stayed with older ideas of love but added new dimensions to the praeceptor amoris, such as adding definition and philosophical discussion to what Ovid had done. They also added to the use of persona as speaker, particularly with Donne's dramatic monologues.
