The Ars Amatoria is a Lehrgedicht, a didactic elegiac poem in three books, in which Ovid teaches the arts of love. Book I addresses men and teaches them how to seduce women. Book II, also geared toward men, teaches how to keep a lover. Book III addresses women and teaches seduction techniques. The first book opens with an invocation to Venus, in which Ovid establishes himself as a praeceptor amoris-a Teacher of Love.
